I think it is a trust, why many coins fail? because investors none the trust and will eventually choose bitcoin. the Bank will make many rules and restrictions so that make our account be frozen.
All banks set a lot of different rules. And if we break them, our account will be frozen. But this will not happen if a person simply uses his bitcoin purse. Therefore, I believe that such banks are useless
As stated banks have got several terms and conditions that needs to be followed to continue usage of their services. But with bitcoin wallet theiris no limitations in having it without a small amount into the wallet. Also it cannotaccessed if their is an internet connection but with bank for such service we need to pay regular charge of using it.
