hodl is one of the best methods for me. and I think it's the most guaranteed investment method. because short-term trading is not something that everyone knows and can do. Therefore, with hodl, we have a chance to make a more secure and secure investment. Even someone who does not know how to trade has the chance to earn a profit by hodling. The important thing is to buy from the bottom and sell from high. but we do not know which is the lowest price and the highest price.
