For me yes, Bitcoin is safer than bank but I'm not saying that bank is not a good things keep our money to them. It is just more like that in Bitcoin savings there is a probability were your amount of money could become x3 up to x10 or more depending on the price value of bitcoin when it goes up rapidly. And banks are requiring many documents while in bitcoin is not.
I do not think so, agreeing that bitcoin can give us many opportunities to double or triple the amount of money we have but this life has two sides, good and bad, bitcoin is similar, it can help our money rise and it can also help our money to disappear. The market during this time is enough to prove what I say, many people have lost a lot of money and can not know exactly when things will return, so I can say that the bank is safer, although our money in it has no great growth but it is absolutely guaranteed and can not disappear absurdly
