Bitcoin is an independent currency. Here you can invest as per your wish and withdraw as per your need. Others take it as a goal. He leaves until the goal is met. It is only your freedom. It is as easy as it is risky. You should choose your own thinking and research style at all times. Then success will come. On the other hand, keeping money in the bank is safe, but you will see how the value of your money decreases through inflation. If you keep money in the bank, how many rules do you have to follow? Again, the possibility of bank failure remains. So I think keep some money by investing in Bitcoin. Will come in time.
I would like to agree with you on this point that the best part of Bitcoin is its security, especially its peer to peer system. It gives us the security of our fund and make independent our fund from the custody of bank system. Even then look at a bank how much highest apr you have got from bank 10% or more ? On the others hand if you looks at the ATH of Bitcoin it is also really far from my current situation so if you invest on bitcoin then you can also gain a good profit from this.
