I often find myself thinking about a simple thing; If you have gold or anything valuable, you're locking it up in a safe. Same with money, you don't keep it all in your pockets, you store it in the bank. You should do the same with bitcoin, either get a dedicated machine or keep it stored in a cold wallet.
Why risk it?
I think that OP knows what to do with it, this thread is 5 years old and I think that there isn't nothing new to advice to OP. That is like the basics of not getting broke easily, diversifying your storage to make sure that when one is compromised, you won't worry about your whole wallet getting stolen.
