Basically if you are only looking for a place to secure your money, BTC will be the answer for it and you should put every money that you have to be in form of BTC as an investment because BTC is far more secure than bank
I don't think so, because no one that will guarantee your bitcoin other than yourself. You can't complain to police or other authorities when your bitcoin was lost if you are living in country where government don't recognize bitcoin. So, if it lost, then it's gone forever. In bank, they can give guarantee to secure your money.
