Many of american people buy bitcoin for their retirement, so they save bitcoin for long term. I have the same plan with them, I still thrust to bitcoin rather than other cryptocurrency. Although people said that save wealth in form of bitcoin is risky but I knew that I take this risk with good reason.
I believe bitcoin will live long and price will increases as time goes by despite of its volatility. This can be a good plan that everyone can follow though. Even it takes high risk, remember that there is no person become rich without taking any risk, even how high it is. Bitcoin can give good profit but remember that you can diversify your investment for more possibilities.
