With bitcoin you know that you can moove anytime your coins being 1 or 200k coins anywhere,at banks you need to ask to them to allow you and have to explain why you wanna to moove those funds,hello the money is yours why you need to explain?
I my self use banks because bitcoin cant pay my bills ,atleast not directly it must be exchanged to fiat .Bitcoin is the most secured option to protect your money even with such volatility.
