$ETH Coin hoarding method: suitable for bull and bear markets. The coin hoarding method is the simplest and most difficult way to play. The simplest reason is that after buying a certain coin or several coins, you hold them without doing anything for half a year or more than a year. Basically, the minimum return is ten times. However, it is easy for novices to see high returns, or when the coin price is halved, they will plan to change or exit. It is difficult for many people to persist for a month without trading, let alone a year. So this is really the most difficult thing.
