So according to this situation which one would be better? I wants some actuall numbers not promises.
Basically the way banks and Bitcoin work is very different, you should not compare the profits of your deposits/investments in banks with Bitcoin.
Maybe you can see on various social media/Google the main reason why Satoshi Nakamoto created Bitcoin.
In short:
Bitcoin was created to allow people to send and receive money digitally without relying on banks or intermediaries.
That's where the difference between Bitcoin investment and Banking lies.
Banks do directly provide interest profits from your deposits/investments, because your money has been transferred by the bank to their credit customers.
Meanwhile, Bitcoin's main purpose is not for investment, as mentioned above, because Bitcoin's growth continues to increase, up and down per second, minute, day, month and year, ideas arise from various groups of Bitcoin users, to trade, invest and so on, it does not affect the 4 year cycle, so don't make the wrong arrow, regarding investment and so on.
If you compare it, the best name is between Banks and Bitcoin in terms of investment, of course my answer is of course Bitcoin, Banks have clear percentage profits, but not Bitcoin, sometimes the profits they get are a higher percentage than Banks.
