“If the only way to make a profit is to get someone to buy your coins for more than you paid for them, you are doing something illegal.”

Uhh, isn’t this pretty much the definition of profit for any asset, selling it for more than you paid? Stocks, bonds, gold, art, etc. all work the same. One can reasonably question whether crypto markets are overvalued, but this kind of hyperbole robs you of any credibility.
