I am sure that some people use their pension funds to jump into bitcoin and they use all of the money to buy bitcoin. But I would say that it's not a good idea and I will call that is greediness because we don't know what will bitcoin do in the future. Bitcoin price itself will still fluctuate from time to time, and we cannot expect to see bitcoin can increase higher in one night, and that is impossible.

I will suggest to that person to use 50% of the total of his pension funds to invest in crypto. 30% to invest in bitcoin, and 20% in the altcoin but he needs to know how to pick the right altcoin, so he doesn't pick the wrong coins for the investment. I am sure that he can found the best coin and he can be able to make a big profit for a long-term investment.
