They do make it easy to give them money.
They just don't want unstable scam bullshit where they have to go through the slog of going to an exchange, selling the coin, and cashing out.. hoping all the while it doesnt crash in the mean time. Everyone tried to cash in on it when it was hot, before the vast majority knew or realized that crypto was nothing but a pump and dump scam, and they all dropped it due to instability and the fact that its a scam.
