I trade enough to 1) either afford paying for the server on its own or 2) not care if it falls short, as this is all speculative.

To be honest, I only just recently started staking wallets on a remote server, so I cannot say how profitable / unprofitable it is. I think having multiple coins staking, with constant internet access, is worth quite a bit to me, so I can turn my home machine on and off as needed.
