I hold bitcoin for the main reason of appreciation. I believe that BTC's price right now is still small that it could potentially rose to a 10x in the future. Another thing is it solves inflation. Instead of saving my money in bank, I put it in BTC and watch it grow as it goes.
You trust bitcoin too much. And that's what is important if you decided to hold bitcoin. That was what the early adopters did and that was a great decision. But I think you should also put some on the bank. Due to inflation, the bitcoin you were holding may decrease in value and will get back and get much profit but what if you need urgent money but the price of bitcoin is low due to inflation, what will you do?
