Een initial coin offering (ICO) is een vorm crowdfunding, waarbij een bedrijf of organisatie (al of niet met cryptogeld als hoofdactiviteit) het publiek tegen betaling digitale tokens (een vorm van cryptogeld) verstrekt. Bij een meerderheid van de ICO's wordt gebruik gemaakt van de blockchain van Ethereum, onder meer wegens Ethereums smart contract feature (ERC20 tokenstandaard). In veel andere gevallen wordt een eigen blockchain gebruikt. Verder is er nog het Waves platform, dat niet alleen zijn eigen cryptovaluta heeft, maar ook ontworpen is om organisaties bij te staan bij hun eigen ICO.[28]
Because the blockchain works by verifying transaction history, and this verification process is labor-intensive and slow, only so many transactions can be verified in a certain timespan. So, if you sell your Bitcoin, but the purchase isn’t confirmed by the blockchain network, and the price of the currency changes, the sale won’t process. You'd have to sell your Bitcoin at whatever the new rate is (if you so choose to sell). Also due to the reality of blockchain, as well as for other reasons thus far unidentified, the Coinbase payout system can sometimes be unreliable. There have been reports of extensively delayed payout periods, and bugs sometimes keep the site from running as efficiently as it could or should. A word to the wise: if you are going to invest in and speculate on cryptocurrencies, do so carefully.​

Smart contract is just a phrase used to describe a computer code that can facilitate the exchange of money, content, property, shares, or anything of value. When running on the blockchain a smart contract becomes like a self-operating computer program that automatically executes when specific conditions are met. Because smart contracts run on the blockchain, they run exactly as programmed without any possibility of censorship, downtime, fraud or third-party interference.
^ Iansiti, Marco; Lakhani, Karim R. (January 2017). "The Truth About Blockchain". Harvard Business Review. Harvard University. Retrieved 17 January 2017. The technology at the heart of bitcoin and other virtual currencies, blockchain is an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way.

In August 2019, Coinbase announced that it was targeted by a sophisticated hacking attack attempt in mid-June. This reported attack used spear-phishing and social engineering tactics (including sending fake e-mails from compromised email accounts and created a landing page at the University of Cambridge) and two Firefox browser zero-day vulnerabilities. One of the Firefox vulnerabilities could allow an attacker to escalate privileges from JavaScript on a browser page (CVE-2019–11707) and the second one could allow the attacker to escape the browser sandbox and execute code on the host computer (CVE-2019–11708). Coinbase's security team detected and blocked the attack, the network was not compromised, and no cryptocurrency was stolen.[39][40][41]

Vaak wordt een proof-of-work-schema gebruikt voor een systeem van consensus op basis van rekenkracht dat bescherming moet bieden tegen manipulatie en vervalsing. Er worden vaak meerdere transacties verwerkt in ieder blok (bij bitcoin bijvoorbeeld per blok alle transacties in een tijdsinterval van ongeveer 10 minuten, dat zijn er ongeveer 3000 in december 2017[5][6]). Zodra een blok gevonden is wordt het openbaar gemaakt. De andere nodes controleren het, en de nodes gaan op basis hiervan en van de inmiddels nieuw uitgevoerde transacties beginnen met het zoeken naar weer een nieuw blok.

The amount of coins scraped increases over time. However, the actual profit achieved in euros or dollars depends largely on the selling price. The prices of the individual coins fluctuate over time. However, these tend to show a growing trend. CryptoGold exclusively transfers the prospected results to VC. So you can use the price fluctuations for yourself and profit from the strong growth of the crypto market!

Most cryptocurrencies are designed to gradually decrease production of that currency, placing a cap on the total amount of that currency that will ever be in circulation.[25] Compared with ordinary currencies held by financial institutions or kept as cash on hand, cryptocurrencies can be more difficult for seizure by law enforcement.[1] This difficulty is derived from leveraging cryptographic technologies.

Until relatively recently, building blockchain applications has required a complex background in coding, cryptography, mathematics as well as significant resources. But times have changed. Previously unimagined applications, from electronic voting & digitally recorded property assets to regulatory compliance & trading are now actively being developed and deployed faster than ever before. By providing developers with the tools to build decentralized applications, Ethereum is making all of this possible.

Any services that are centralized can be decentralized using Ethereum. Think about all the intermediary services that exist across hundreds of different industries. From obvious services like loans provided by banks to intermediary services rarely thought about by most people like title registries, voting systems, regulatory compliance and much more.

Due to the high number of new requests the answering of the support ticket is delayed. We are working hard to reduce the number of open tickets. We would like to ask you not to provide multiple tickets for payouts. All tickets will be read by support and will need to be processed. This only prolongs the time it takes to answer the tickets. Payouts will still be made on an ongoing basis. Due to the instances in the past, these will be checked carefully before the release, which will delay the payouts.
These decentralized applications (or “dapps”) gain the benefits of cryptocurrency and blockchain technology. They can be trustworthy, meaning that once they are “uploaded” to Ethereum, they will always run as programmed. They can control digital assets in order to create new kinds of financial applications. They can be decentralized, meaning that no single entity or person controls them.
In mining, bitcoins and old coins are extracted by providing computing power. Coins can thus be generated passively. Special “miners” with particularly high computing power are used for efficient prospecting. Various suppliers rent or sell these miners for a fee. The amount of the mined coins depends on the booked or available computing power as well as the difficulty of the network.

Wat betekent een halvering betekenen voor litecoin


Litecoin, however, uses the scrypt algorithm – originally named as s-crypt, but pronounced as ‘script’. This algorithm incorporates the SHA-256 algorithm, but its calculations are much more serialised than those of SHA-256 in bitcoin. Scrypt favours large amounts of high-speed RAM, rather than raw processing power alone. As a result, scrypt is known as a ‘memory hard problem‘.
The novel hybrid consensus-based TrueChain tends to rely on POW consensus for random node selection, instead of using the slow chain mechanism to ensure security like Thunder.Although TrueChain has released dozens of Dapps, the number of its addresses (including active ones)and transactions is small. After the mainnet is launched, the project has run out of short-term bullish factors, which, plus the underdevelopment of its ecosystem, leads to a price slump within a short period of time. It will take some time for investors to regain confidence.
Litecoin is an open source software project released under the MIT/X11 license which gives you the power to run, modify, and copy the software and to distribute, at your option, modified copies of the software. The software is released in a transparent process that allows for independent verification of binaries and their corresponding source code.

Later werd in andere cryptogeldsoorten gestreefd naar het decentraliseren, waardoor censuur op de munt bemoeilijkt zou worden, en de anonimiteit vergroot. Zo ontstonden Namecoin (een poging om met gedecentraliseerde DNS te werken), Litecoin (die scrypt als proof-of-work gebruikt en snellere transactiebevestigingen kan versturen) en PPCoin (die een hybride proof-of-work/proof-of-stake met reservecodeblokken gebruikt, en een inflatie van ongeveer 1% kent).[7] Veel vergelijkbare andere cryptogeldsoorten ontstonden daarna in rap tempo. Ze hadden echter niet allemaal succes omdat veel soorten maar weinig vernieuwing hadden, en de markten al volliepen met de al bestaande cryptogeldsoorten.

In May 2018, Bitcoin Gold (and two other cryptocurrencies) were hit by a successful 51% hashing attack by an unknown actor, in which exchanges lost estimated $18m.[citation needed] In June 2018, Korean exchange Coinrail was hacked, losing US$37 million worth of altcoin. Fear surrounding the hack was blamed for a $42 billion cryptocurrency market selloff.[72] On 9 July 2018 the exchange Bancor had $23.5 million in cryptocurrency stolen.[73]

LTC is a tricky one to predict. Consider that LTC has been leading the way earlier this year and not BTC. Although BTC gets the news, LTC was usually the first to move (pump) with BTC then eth/alts. LTC topped out June 22 '19 with BTC following June 26 '19. While BTC is playing more of a traditional DOW theory thus far (and I use traditional in the loose sense...

For miners and enthusiasts though, litecoin holds a much more important difference to bitcoin, and that is its different proof of work algorithm. Bitcoin uses the SHA-256 hashing algorithm, which involves calculations that can be greatly accelerated in parallel processing. It is this characteristic that has given rise to the intense race in ASIC technology, and has caused an exponential increase in bitcoin’s difficulty level.


Coinbase Pro charges 0.1% to 0.25% for taker trades, and no fees at all for maker trades. As long as you place limit orders, you won’t have to worry about paying a fee. What’s more, if you have a Coinbase account, you already have a Coinbase Pro account. Simply log in to Coinbase Pro with your Coinbase credentials. Better still, you can transfer funds instantly between Coinbase and Coinbase Pro.

Cryptogeld is doorgaans gebaseerd op peer-to-peerverbindingen en gedecentraliseerd (zonder centrale server). Alle varianten van cryptogeld zijn gebaseerd op het eerste concept: de bitcoin.[7][8][9][10][11][12] Cryptogeld is doorgaans ontworpen om te functioneren als een betaalsysteem zonder inflatie doordat er in totaal maar een beperkt bedrag in omloop wordt gebracht.[13][14] Er zijn echter een paar soorten cryptogeld zoals Peercoin (PPCoin of PPC), die wel een kleine hoeveelheid inflatie kennen.

There are also purely technical elements to consider. For example, technological advancement in cryptocurrencies such as bitcoin result in high up-front costs to miners in the form of specialized hardware and software.[87] Cryptocurrency transactions are normally irreversible after a number of blocks confirm the transaction. Additionally, cryptocurrency private keys can be permanently lost from local storage due to malware, data loss or the destruction of the physical media. This prevents the cryptocurrency from being spent, resulting in its effective removal from the markets.[88]

Ethereum was announced at the North American Bitcoin Conference in Miami, in January, 2014.[9] During the same time as the conference, a group of people rented a house in Miami: Gavin Wood, Charles Hoskinson, and Anthony Di Iorio, a Torontonian who financed the project.[9] Di Iorio invited friend Joseph Lubin, who invited reporter Morgen Peck, to bear witness.[9] Six months later the founders met again in a house in Zug, Switzerland, where Buterin told the founders that the project would proceed as a non-profit. Hoskinson left the project at that time.[9]

So the app is pretty great when it comes to buying crypto, they can give you the funds immediately at the current price of the crypto, so high purchasing fees and selling it on a quick time line are virtually non existent when you are making small orders, most likely biggers as well. Not so fast... if you purchased it through your bank, because the allowance is higher on it than 25$ for a new card, your funds are basically frozen for 2 weeks. You can not cash out, nor you can send crypto to another wallet, so if you are looking for something to transaction with this isn’t the greatest app to do it with. I’m stuck with funds frozen for already 10 days, and now I have to wait another 5 for the banks to clear it, when on the card is faster, but you are stuck with the same high cost for selling it which comes out to bite you in the but for the fees. Yes, I can sell it and wait at usd wallet so the price doesn’t fluctuate, but again, if you want to get the funds out they are the power delay and have no intention to speed the process and again, you are in lala land waiting for it! Before, it’s not used be this bad but seems like delays and restrictions will expand. For the high cost of buying, and buying always at a higher price than it actually is, it makes even more worthless, even waisting time and resources just on trying to obtain some btc. There are better apps and cheaper apps that don’t cause you such issues. Good luck crypto fans

Vroege pogingen om versleuteling (cryptografie) met elektronische valuta te combineren stammen van David Chaum, die DigiCash en ecash bedacht om elektronische geldtransacties versleuteld te kunnen verzenden.[20] De eerste echte cryptomunt was Bitcoin dat in 2009 door een softwaremaker met pseudoniem Satoshi Nakamoto werd ontworpen.[21] Dit systeem gebruikt de hashmethode SHA-256 als het proof-of-work-schema.[22]
Cryptogeld is waarde in de vorm van een bedrag in een cryptovaluta, of – met een Engels woord – cryptocurrency. Dit laatste is een soort digitale munteenheid, die vaak gebruikt wordt als alternatief geldsysteem voor de reguliere geldsoorten. 's Werelds bekendste cryptovaluta is de bitcoin. In hoeverre cryptogeld werkelijk geld is, is omstreden. In Nederland heeft bijvoorbeeld de bitcoin de juridische status van ruilmiddel, maar niet die van geld.[1]
