However as part of durability, BTC will not erode over time but I am extremely worried about hackers and governments taking down exchanges and basically stealing all of our BTC via the law or via raw theft.
I don't even know if it is safer to leave BTC on something like Binance or on a ledger, because both are attacked by hackers and by the government. That is hard to overcome.
Something that you are worried about, of course, has a basis, everyone definitely doesn't want to lose their money easily. But you have to really understand that bitcoin is a risky investment where you need to care not only about its price volatility, but not about its security. There is some good advice you should read if you are worried about storage wallets.
Reminder: do not keep your money in online accountsIf you are concerned about the best method to store your bitcoin safely, then you should pay enough attention to security advice. After all, binance is just a centralized exchange, it is not a secure wallet
[not recommended], so have a wallet that gives you full custody instead of 100% trusting a centralized exchange.
