Crypto investors have already invested in bitcoin, I can hardly call that a coward's move.
There is nobody who is investing 10 bucks in bitcoin and expects to be a millionaire.
I think they can be called cowards if they invested without a goal but every one of them surely has one goal "to be a crypto millionaire or billionaire" in the future. LMAO there is no future with 10 bucks and if someone invested in Bitcoin or other forms of crypto currencies with that amount and expecting to be a millionaire or billionaire someday, that person must be insanely crazy. An investor can be called as a coward if he/she invested on crypto currencies with all of his/her money and nothing left to him/her except a few and he/she is expecting a good profit from it, Now that's what you call a coward. And if an investor only invested the money that he/she can afford to lose then that is a wise investor and most of those investors with that kind of mindset end up being successful in terms of monetary or financial profits in the future.
