I have done enough research to know it is a hassle to get signed up, the two wallets I reviewed did require my bank details, but even with other methods, there is a significant hassle getting it all set up, buying coins, keeping track of new tech issues, and no protection or guarantee/security like with US FDIC insured institutions issuing credit cards.
I like the fact that my bank assumed a fraudulent charge had been placed with my Visa when a $921 USD charge for women's clothing at some online store in China appeared, and took proactive steps to protect my account, and limit their liability. Bitcoin is not going to give that level of reliability, guarantee, refund, and protection. You are welcome to use it, but not me.
