I think trading is better than buying and holding cryptocurrencies. Because there are always some opportunities for income. If you buy and hold any coin, there is not always a chance of income, there is a possibility of loss again. So I think everyone should give more importance to trading. However, it is possible to make a profit by buying some coins and holding them for a long time. Such as Ripple, Monero, Tron, NEO, cardano, NEM, dot.
