I would consider it if at MINIMUM the following are in place:
- Some kind of insurance similar to the FDIC insurance that protect depositors at US banks,
- A guarantee that the CEO goes to prison if depositors' coins are lost, regardless of whether the loss was due to bad business decisions, unintentional negligence or criminal intent.

Nope. I will never give a third party control over my Bitcoins. It doesn't matter how much interest they are promising me annually. My coins will always stay offline in MY control

Why would you give your coins to a Bank when you can just have them with yourself all the time???
And about interest rates, Bitcoins themselves give much better interest than mentioned in the title, so obviously a no from me too...

I'm sure it's already been stated but isn't the whole point of bitcoin that we can be our own bank? Besides, if bitcoin is adopted worldwide and it continues to grow bitcoin will naturally gain interest and much more than 10% a year. Haven't we already grown ny much more than this this year alone and we didn't need to let filthy banks hold our coins.

Even if one to assume bitcoin overcomes volatility it is economically less suitable to be an instrument of debt due to its disinflationary nature. Banks would need to charge interest rates above appreciation from disinflation. This would indicate that only high interest loan shark "banks" would have a business model where they could share in profits due to bank overhead, volatility, and the extra infrastructure. I would not want to invest in any of these businesses even if they provided a service gouging the poor and uneducated needing payday loans.

There really isn't any viable ways for banks to securely promise those returns with bitcoin.

If it's a legit source then why not? Like lending for margin trading such as magnr or haobtc with mining service

The main reason for me to say no is bitcoin is anonymous and decentralized an its bank will be same. Without any physical And central part bank can't work as there should be someone responsible for the security of our bit coin.

There shouldve been an IF with that question.

That is a big percentage for a bank though. 10 percent is huge. Hmmm I would say no for now.
The price is not stable. You can profit that 10 percent through exchange. Maybe a littlr risky but still a profit. Plus you dont know what could happen. What if it falls and you want your bitcoin where the price that you started putting it in the bank.

Really? They offer that kind of interest rate on accounts within their website?

In one way that would make more sense because it is an exchange and thus they can take some of their fees and convert them to interest as a means of generating interest in their site, but that still seems like an exceptionally high number.

Yes, who the heck would give you this much return on your investment? This wouldn't be sustainable at all. Some pyramid scheme that would last limited amount of time maybe, but a legit business to pay you 10%, I don't think so!
