I think crypto is really for all but the the market is for the smartest. The market is not stable making it difficult to predict therefore before taking any decision there is the need for you to know its merit and demerit. If you are a "coward" you might not be able to make some decision that might turn things around for you.
for the exchange, including crypto-exchange, a smart coward is needed to trade. exchange-this is not a game of roulette, here you need careful action with the main goal is not to lose money on it .
