Actually, I think this is the best time to spread the gospel.

Community quarantine is still happening in different parts of the world.
They cannot make their transactions outside and they will rely on the internet.
It would be best to first target the services.
Once they have the option to pay in bitcoin then maybe, even just for a little chance the people will use that option.

But think about it, if there is no option to pay thru bitcoin then what use can it be?
You say just an investment. But it was not made for that.
If they lose money they will just withdraw it which makes it look like a bank. Why not just pick bank instead? It will be easier.

You have to give them a better reason for bitcoin to be kept.
