Will in addition to banks paying interest if you save money not more b but at least they pay. banks also provide more protection to its customers, if you're fooled by a merchant. you can report the bank and they will freeze fraudsters wallet and your money will be refund in you bank that's cool but in bitcoin world situation is something else. All bitcoin services comes to loot money not to profit you.
You are right about that, banks offer some better protection and if case of scam they can do something. Only its not like that in reality, scammers don`t have bank accounts, they in most cases don`t have nothing on their name, they know for all the tricks. Maybe with cold wallet and safe place of your own choice you can protect your money better then the bank.
It`s not true that bitcoin services are scams, there is good ones, and if people have a little brain they will come here and inform about some service before they give money. That is right thing to do, and you should do it and you will not be scammed.
