The best interest percent is here in bitcoin. You are the one controlling it. Yes. That is what is cool about it. Sell high, buy low.  It is still faster that way than waiting for an interest in a bank. Yes bank gave the security in your money. But what else do they do with your money. They profit more for investing it in different things. Then give you just the very small percentage for lending your money to them.

it's right agree with you
the interest of bank is very low, can't keep up with inflation rate, but bank give your guarantee your money is safe store at bank.

i think if you save/invest your money at bitcoin you will not find always in profit.

If you are still afraid of investing into bitcoin, there are still other investment types you can use like stocks or mutual funds. They have risks so you have to think very carefully before you engage. And a tip on investments, do not put all your money in one place. So invest some in bitcoins, some on mutual funds, some stocks.

both of them is good then save 70% of your money and invest 30% of your money
so if you lose your invest you still have 70% of your money, or if you get profit you can save the profit ast your saving account
