Long term it's exactly what you should do unless you truly believe that the USD is going to be as valuable as a security as it is right now in the long run (it's not). One thing that many people forget is that most bitcoin is owned by very few people who go in very very early. They will not need to sell even if it was cut on half from now and they do not have to worry about inflation. If you can do that in the long run bitcoin will gain trust and thus be less volatile or even live with the volatility (as we used to do with normal fiat currencies)
