All profits anyone makes on cryptocurrencies comes out of the pockets of other "investors". A lot of them will be like this, addicted people who were lured in by dishonest promises.<p>Cryptocurrency is a negative-sum game. There is an inflow of cash into the markets, and two outflows: Regular traders cashing out, and miners cashing out. The market caps, the supposed dollar value of your holdings, it is all imaginary. The only thing that is real is money being paid in, and money going out.<p>And unless you sell and take your profits, that outflow is not going to you. It is going to someone else. And if you do, the money comes from somebody less fortunate.<p>The only ethical thing is to not get involved.
