I've only bought $100-$200 in stuff over the years, at about $50 at a time. Would it really be that bad to send it directly to Coinbase so I can cash out?
I would be more cautious if I was doing highly visible, illegal things, but I don't think they're going to backtrace stuff for such a small fish, and I'm worried about entrusting that much money to a tumbler.
send them to another fresh electrum wallet on tails first and then to an exchange. you already have that much money so spent a little bit of it on your future to avoid ruining it.
