Did anyone think at this? How would a bank work? How could you loan bitcoins and get interest for them in an economy with just 21 milion BTC limit?
It is not enough to write a bitcoin-bank and expect that others will argue on this topic. It is necessary to explain the essence of the topic in more detail. The forum already has a theme raised by the POV team, where this team wants to organize an ICO to create a similar bank for digital coins. They offer only to tell them certain information about your coins so that these coins in your wallet can be blocked for the duration of the agreement with their bank. For this, the bank undertakes to pay interest in coins. I wrote to them many times and asked about the material interest of the bank itself, where the bank will take profit, but did not wait for an answer. Therefore, I am very skeptical about the ideas of creating such banks.
