Just known that whatever means you choose to save you money with, it should be well secured. We have heard of many Bitcoin wallets hack here on the forum. But just because we haven't seen one and don't pray for such, doesn't mean its not possible with Bitcoin. Make sure to keep your keys safe and away from the reach of others and the internet. Again. You can diversify your savings into two.nits even better that way so if one goes wrong, you can have something to fall back on. If you choose banks in Nigeria for savings then make sure you use those standard banks that have big branchs and head offices here in the country.. if it's crypto then keep your keys safe. Just remember anything if possible when it comes to hacking or losing of funds. But that's not our portion..
I agree with you, There's no anywhere you can save your money and that place can't be hacked, even can be hacked, the only thing we should pray for is not to overcome such things, talking about buying Bitcoin instead of saving money in the bank, it is good to invest the money you are not going to use or the money you will not touch even when you have a problem in bitcoin but it is all the same as banks, the only different is that when you buy bitcoin and you hold for a long time you are going to make a good profit if the price is Rise but thinking that the banks are not safe or wallet is much safe than bank I don't believe that.
Both wallets and banks have advantages and disadvantages, we all know that banks sometimes have some things that are annoying and they have many excuses, but I believe if a bank is hacked and all the money in the bank is stole that doesn't affect those who have money in the bank, the bank will be the one to be responsible for that and I believe the bank can handle the issue, if a wallet got hack and your bitcoin they steal your bitcoin I don't think you can get it back and you can't hold anybody responsible for it.
