Long-term investment: An investment held for more than 5 years. Although few people say that they are short-term investors, there are actually many such people! In the context of long-term investment, entrepreneurs may invest in strategies, research, or some projects that have high personal returns, but shareholders expect relatively low monetary returns.
Long-term investments should coincide with the cycles that are caused by bear and bull markets. Thus, it is necessary to make investments at the end of the bear market and the beginning of the bull market, and after reaching high, it is necessary to sell your coins and wait for the start of a new cycle.
I think it is not easy to identify the end of bear or bull cycle with 100% accuracy but what we have learnt from our experience that Bitcoin usually falls 80-85% from its all time high before it starts recovering, Hence we should start accumulation around that level and continue buying on every dip. This is what I think is right strategy based on historical trend of Bitcoin but it is not necessary that history always repeats itself.
