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
Yeah that's the right thing. We can sell your bitcoin whenever we want to. It also has a positive impact and negative effects for us. Positive impact we can get is we can get a bigger price than the price now,. But it also depends on the price that occurred
If you see higher price then you bought then you should sell it without any hesitation as you have already made profits from it and you always have an opportunity to buy it again when price drops.
