I use Bitcoin to function as my own Bank, i've had alot of hassle from actual banks doing this and actually the Bitcoin economy isn't anywhere near mature enough to side step fiat.
I do this as well. It's nice to save up without having to worry about the banks taking your savings or even taking a risk in that. I use bitcoin to save up my money, just in another currency, because I believe bitcoin will grow in value in these years to come.
