*Insured up to $100,000

Next time read the terms of services of banks before writing stuff like this. Most banks will only insure up to 6 digits of money which means that it anything happens to the bank and you have millions of dollars, you will lose almost all your money.

We know Bitcoin is decentralized (because I just refuted that point), so there is not supposed to be anyone who guarantees you if your coins are stolen.

Besides, banks cannot insure people when thieves steal cash from them, so this construct really only exists in terms of bank accounts (which is not hard currency).
