I still believe in the bank to save my shopping money and my daily needs, but when investing I am more inclined to bitcoin even though the price is uncertain I am more comfortable saving my savings in bitcoin. because my main reason is the interest rate in the bank is small and there are too many admin fees
The only reason for me to trust the bank is that in any case of mishap in the transaction , i can call the bank and resolve my issue. Also i don't like to put more money in the bank as that money is being monitored by the tax authorities.
Bitcoin, on the other hand is my own money and no one in the world know how many bitcoin i owns. If i lost the private keys, its my own fault and i would never get my coins back. That's the only risk with bitcoin.
