I do not consider investing in a bank as an advantageous measure compared to crypto-currencies. from the bank you receive a trifle and you lose opportunities more profitable to dispose of the capital
yes we do not consider the saving in banks as the investment while keeping our money in bitcoin is a like investment and saving both. We get much mmore opportunities of getting profit if we invest in bitcoin. While banks may not enable you to get some extra income from your money which you will be able to spend for a luxurious life.
If anyone have money to invest for a long time then they have to invest them in bitcoin and wait for a longer time then their luxurious life will be started.
