HandCash is a privacy nightmare, all ID's and wallet addresses and transactions are connected via their server, (your phone number, full transaction history ready for KYC with the ability to potentially freeze your funds as they seem to have proprietary backups, in addition, their wallet depends on their serves to broadcast your transactions), I've been told this is a feature, not a bug.
While their ToC may protect you, it does not protect you from whoever gets access to the data, it's a privacy boondoggle that could be a bigger privacy concern than facebook or google at scale. The founder has said he'll sell out if the offer is good, that didn't give me any confidence when it comes to financial privacy data ending up in the wrong hands.
My preferred wallet is Electrum, conomi has a mobile app but it cant send to payment addresses, Edge works too although I don't use it much.
In my opinion, the only way to acquire BSV that makes it go up in value is to develop something that encourages people to send it to you.
