When trying to make the most out of the cryptocurrency you have, there are a number of strategies you can employ. One of these is known as crypto pump and dump strategy from crypto pump and dump groups. In this case, an individual or entity artificially inflates the value of the currency, stock or commodity they have. In our case we do this with cryptocurrencies, because it is not regulated and hence legal by the SEC or other financial institutes. This answers the question: ‘are crypto pump and dump groups illegal?’ – the answer is clearly no, crypto pump groups are legal.
