I really do not like the fact that I can not use it everywhere I want to spend money. It is very convent for me to access my bitcoin accounts and get my money, but because everyone does not accept the currency, it complicates things.
I don't think there is any complication in spending bitcoin, if you cannot spend it directly you can sell it anytime and convert it to fiat currency and if you want to spend it directly then you need to move to Brazil
