I don't have an exact strategy for investment. For me, the strategy should depend on the current situation in the market. In the bullish season, I prefer to invest short-term, holding for months or weeks. I never buy a coin to hold for years in the bullish market because we know there will be a bearish market after this bullrun. While in the bearish season, it is the time for me to buy coins to hold a long term since most coins have a very cheap price at that time.
