Someone from Zimbabwe here - I endorse their statement: trust the banks. I lost my money to a bank closure in early 00s, eventually got some of it back from the zombie entity that the central bank resuscitated. The CEO of a Zimbabwean crypto-exchange[1] "lost the password" of a cold wallet (wink) a year ago - the deposits therein were lost with no recourse; the exchange is struggling with solvency[2]. So yeah, if you're not going to stuff money under your mattress, give it to a bank before going full crypto.
1. Golix - you might have heard of it as it was offering the world's highest USD:bitcoin rates. The fine print was that you couldn't get USD out of Zimbabwe
