In most part of Africa hardware wallets are not only difficult but expensive to get apart form using custodian wallets like trust wallet and metamask is there an alternative software that can help hodl Bitcoin in a flash drive. or otherwise
The flash doesn't only holds bitcoin but their seed phrase can be stored inside the flash drive maybe as a backup but is not trusted to use because whenever you have those seed phrase stored inside, and slot in your flash drive to any computer that has virus it might get corrupted this may lead for you not have access to the wallet again which would results in loosing the funds stored in that address since you don't have access to the private keys again.
This is not advisable imo.
