Actually, I've done that but even if BTC and ETH went to zero, which I think is extremely unlikely, the payments I have to make are nothing I can't handle. At this point, I'm very comfortably in profit. Next year, I should be sitting pretty.

I would advise anyone against leveraged positions so large that things going the wrong way could wipe you out. Nailing speculative trades like this is difficult enough without a looming threat of financial catastrophe in the back of your mind.

Don't risk money you can't afford to lose.
