please tell me the name of some electronic banks!
If it is your national currency can deposit your money into the bank in the country you are living in and it can be profitable monthly for you.
But electronic money has a bank yet?
When depositing your e-money into electronic money banks, is it profitable and safe enough?
There are crypto exchanges where you can deposit and withdraw both cryptocurrencies and governmental fiat currencies. Some of which also offer lending functionality, allowing you to earn interest similar to classical banking.
While you
can store money long term in a crypto exchange (I guess what you would call an electronic money bank), you definitely shouldn't. Trusted exchanges have failed in the past and trusted exchanges will fail in the future. So unless one wants plans on actively trading, the risk of keeping money on an exchange is not really worth it.
