To limit the risk of investing in bitcoin, you should invest in a long term, so that you can be able to benefit from the bitcoin when the price reaches a new ATH. Short term holders are the ones that are involved in the high risk of bitcoin volatility, because they will not be able to be patient with themselves because they are looking for quick profit, and when the market goes against their will, they will panic and sell. Anyone that I am introducing Bitcoin to, I only tell them to invest in a long term, and if they don't listen to me, I will not be blamed on whatever happens to their bitcoin investment.
