it's probably going to hit 5k this year

I don't think it's gonna be this drop -- seems to be stabilizing around 8 and keeps trying to inch back up

wait till Tether goes under or some other MAJOR FUD

is it "possible" yes -- but it's one of those let the machine run for X # years to reverse the key type deals

keep an eye out for any exploits around public keys and be ready to create a new wallet just in case

but otherwise sounds like you've learned your lesson with minimal loss

good luck
