Where do you think to save money? In banks? I think it much more profitable or earn to save money in bitcoin that banks because you are earning in banks just a little bit not like in bitcoin if you have a patient to hold and if you can take a risk you can earn by holding or saving money using bitcoin so that I must prefer to invest my money in bitcoin than banks.
You only think about the profit but you dont think about the risk . yes you can earn alot of profit in bitcoin but do you think you can earn all the time ? No mate . your invested capital could also go down sometimes due to the effects of volatility and do you think that is called saving ?
A real saving is that you kept your money in a stable condition when it does not decrease but it is only increasing as soon as you put another amount on your purse or bank/piggy bank
