ScamCoins- Clearly coins that have been created to scam you out of your money. There are quite a few of them already and the list will continue to grow. There are a few characteristics that scamcoins will typically have. The Anatomy of a Scamcoin lists these characteristics. Some of the coins listed below are already long gone and out of commission. This is a compiled list of many lists I’ve found on the internet, so I don’t take credit for the evidence or accusations. Sources are sited at the bottom of the page. Special thanks to the creators and to those who contributed in those posts.
CoinMarketCap.Com– A website that lists all the cryptocurrency markets that meet a list of 3 criteria in order to get listed. The three criteria are: Must be a CryptoCurrency, must be traded on a public exchange that is older than 30 days and with an API available, and must have a public URL that displays the total supply (total mined so far). While some coins don’t exactly uphold to these criteria, the main question is Why is coinmarketcap listing scamcoins? Is the evidence people bring forth not enough? The only positive that comes from these scamcoins being listed on coinmarketcap is we get to see how much money is being dumped into nothing. So if you’re going to invest in these scamcoins, please send your money to me instead or donate it as it will go towards a much better cause. Some coins listed in green may not be scams. Is your project on this list? I’d love to hear from you.
Premined- Coins that were mined by developers or maybe even insiders before the public launch of the coin. This type of action is full of suspicion, however there do seem to be some legitimate coins that have been premined. Some of the pre-mined coins on this list don’t elaborate as to why they’ve been tagged as scamcoins just by being premined. These details will be updated here once found. It is a touchy subject as to the claims of any premined coin is a scam, so those listed are listed loosely and mostly because they are in the scamcoin thread.
Superblocks– Blocks that when solved, reward the miners with a ridiculous amount of coins in comparison to any other “regular” block, thus giving early supporters a massive benefit if the coin succeeds. This is certainly unethical.
IPO- An Initial Public Offering. The first sale of stock by a company to the public. A company can raise money by issuing either debt or equity. If the company has never issued equity to the public, it’s known as an IPO. Companies fall into two broad categories: private and public. The fact that this has made it into cryptocurrency is ridiculous and one should consider most if not all IPO AltCoins as scams.
