how to save everyone's money differently, saving using bitcoin in my opinion has a high risk of losing a lot of money that you save, like the current example of bitcoin prices going down very deep, I prefer to save money in stocks and gold.
Even in Stocks also the prices goes down, their are even crash in Stock market also, as you can know last so many times stock market also got crashed and lot of stock holders money went zero. But in bitcoin if you hold for long you can surely get your price and even profit also. That is why investing and saving in bitcoin is good way of earning profit.
