Trading is not really for beginners because at first they are unsure and unskilled about crypto trading capabilities. Moreover i think they can be efficient if they study trading for few months perfectly.
Also how easy is crypto investing? You can't buy good coins at a dip! So you need to have sure skills to take every step that is profitable.

Moreover you need to be a sufficient time holder to profit in bull markets. In the bull market almost all tokens increase in price, but especially top coins increase in price, so if you hold on to good projects you will get profits.
