Obviously banks will always put a interest rate which is profitable to for them and not to us. This is really a joke where you keep your money at the interest rate of 1.3% while on the other hand the same bank will distribute the money as loan to other customers at the f* rates of 13% - 15% depending on the type of the loan they are taking. I mean thats ridiculous they earn all the way 10% commission by using our own money. Its better to take loan license and spread the eggs by all yourself. Earn yourself and keep the banks drained with your account. The devils of the financing sector!
Not only that the interest were too low, some banks requires you to keep all the money without withdrawing them for such a long period of time in order to gain interests. 1.3% is still high as majority of the banks only give 1.25% with a maintaining amount balance of $20K. If you want a much higher rate, then go to a not well known bank where you will only share rates with few investors. However, this will put you much at risk once the instituition won't able to attract people that willing to trust their money in it.
When investing in bitcoin, no one guarantees profit and safety of funds. You can both earn 100% and lose everything.
That's where financial institution comes in, it doesn't guarantee you to earn profit through their ridiculous rates but it keeps you assured that the money you put in it is safely secured.
