An anonymous reader writes The editor of a Bitcoin advocacy site believes the proliferation of altcoins (cryptocurrencies other than Bitcoin) is harming Bitcoin's long-term potential as an alternative to traditional currencies. Posting at BadBitcoin.org, a site that seeks to expose online scams that target Bitcoin users, the pseudonymous ViK compares altcoins, including the Internet meme inspired Dogecoin, to a pump-and-dump scheme where developers create their own version of the Bitcoin wallet and blockchain and then "pre-mine" or generate a significant number of cryptocurrency units before the altcoin's official release. Later, when their value has risen, the pre-mined altcoins are exchanged for Bitcoin or in some cases converted directly to cash. While critics of cryptocurrencies in general might find ViK's comments about the altcoin "tulip" mania ironic, the self-confessed Bitcoin fan is nevertheless calling for an altcoin boycott: "The easiest way to stop them is to not participate. We all know that they only have one purpose, and that is to make Bitcoin for the so called developers."
