Russia-based cryptocurrency exchange YoBit has announced a scheduled pumping of coins selected at random. In its tweet, YoBit gave no specific reasons for its action, wherein \u201cwe will buy one random coin for 1 btc every 1-2 mins 10 times (total buy amount \u2013 10 btc).\u201d The exchange, which lists thousands of altcoins, also provided a timer 22 hours prior to the trades. As of this writing, there are six hours left before execution of the scheme. https:\/\/twitter.com\/YobitExchange\/status\/1050035464609124352 We can only wait to see the effect on whatever coins are selected, but the tweet is notable for its unusual nature. Usually, when an asset is bought in the hopes of spurring demand from other investors, it is done more discreetly, so as to sell at a peak. Last February, the U.S. Commodity Futures Trading Commission (CFTC), which has classified cryptocurrencies as commodities under its jurisdiction, had already warned the public of pump-and-dump scams, saying, \u201cAs with many online frauds, this type of scam is not new-it simply deploys an emerging technology to capitalize on public interest in digital assets.\u201d It remains to be seen, however, how regulatory agencies will react, given the forthrightness of the exchange. Commenters on the YoBit tweet expressed disbelief, amusement, and outrage, as well as cluelessness. Several users on reddit have confirmed the existence of e-mails sent by the company, with address email@example.com, indicating that the exchange had not been hacked. Already, trading platform Coinigy has tweeted\u00a0its plan to delist YoBit from its network of cryptocurrency exchanges, \u201cdue to overwhelming negative experiences as documented on social media and forums, among other reasons.\u201d However, it said it would be \u201casking for feedback first. As a popular platform in the crypto trading space, it is essential for us to be diligent and not promote sites that may harm our users.\u201d YoBit has been operating since 2015.
