Banks have been around for centuries and bitcoin has only been around for 13 years. Before bitcoin arrived, did you rely on banks? I don't believe you don't have any bank account, I don't believe you never use a bank in your life. Bitcoin is amazing and everyone should have some bitcoin if want good future that is my sincere advice, but the bank is also very important to us, we should not get rid of it completely, just don't put all our trust in it.
I think BTC needs more time to evolve its number of transactions, for me this is very important
If we one day reach to a volume that is close to worlds banks all total, then we could worry about the increased energy usage, but we are not there now, and yet people are still worried about it. We should be looking into not just dropping the amount of energy we use, but also we should focus on finding a way to fix the bad ways we find energy, we need to use energy but produce it in a clean way.
