If you have money in the bank, you will have to face all these problems. If you have money in the bank, then you will have to answer various questions when you want to withdraw money. You may not be asked to answer any questions to withdraw this amount of $10, $100, but whenever you go to deposit or withdraw $10k, $100k or more, you will definitely have to face various questions. If you can answer the questions given by them correctly with evidence, they will credit you. Moreover, the bank will never credit you, then they will check all your evidence, work type, how you earned money, everything. In short, the bank is not safe for you and the bank always shares the ownership of your own money with the government.
But whenever you invest in Bitcoin, you are the owner of your Bitcoin. You can transact any amount of Bitcoin at any time and under any circumstances. No one will face any questions from you. So always think about investing in Bitcoin and try to keep cash less and also think very little about keeping it in the bank.
