Compared with the proceeds, it is worth investing in bitcoin. In my country, when you deposit more money, the bank will call you to let you invest. Some of these investments are highly risky. At any time, we should not think that banks are a service organization. We should know that banks are the biggest profit making institutions.
Yes you right, if you have big funds in the bank, usually the bank will call you and offer for long-term investment with certain interest, but during that period you can not take your money, for safely I think investment in bank is safer than bitcoin, but for the flexibility and the possibility of big profits in investing I prefer bitcoin
