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..
