The best bank is crypto currency

I didnt know much about crypto currency but when I was introduced to and and I also did my own research I reliased that crypto currency is the best bank that we should start saving with. I remember I saved with a bank in my town which has the highest interest rate so I taught saving there will much more good but later If I had know i shouldnt have saved there because at the long run I didnt get the money I was suppossed to get and also I didnt get all the money I saved in the bank which means I incurred a lot which was not the best. But crypto currency is good in a way that if the crypto increase your money also increase and if it decreases you money will decrease but is best to buy it when it decrease so that when it increase you will get a profit i think this is more like a business or what do you think?
Life must be easy with crypto currency and the government should try and work with most of the crypto currencies so that they can get more profit from it and use it to run their business and it can also help to bring more money into the country..
