So far, every fiat currency in the world is inflationary. It will always decrease in value overtime in the long run. Its a guaranteed loss !
Whenever you sell bitcoin, you are buying a fiat currency; making sure you will lose in the long run
TLDR: JUST HODL BTC
The best idea is hold your money in different currencies (including criptocurrency) and hold in different places. Following this way you will minimize risk to loose money
not necessarily ! not much point on holding an asset thats guaranteed to depreciate
