Planning to head back to sleep...

Keep an eye on possible pullbacks after 12:30 and 1:30. I feel like it'll test 613 and 611 to confirm the breakout validity.
The entry position is pretty bad. If you have heavy long positions that are currently in profit, consider reducing some — whether by 30% or 20%, cutting a bit never hurts. If there's no pullback and it goes straight up, you only miss out on part of the move. If a pullback does happen, at least you're not caught off guard.
BTC is currently at a boundary line. For now, I don't see a very high price—only around 633. If you opened a short near 620, you can set a tight stop loss, say at 62350. If the pullback tests 613 and 611 but doesn't break them, then the short should be closed.
For ETH, watch 1720. If you try a short, set the stop loss around 1735.
This isn't encouraging shorting, because the long move doesn't seem to be over yet. If you don't have longs and don't want to wait for a pullback, a light short position just to catch the dip is okay.
I don't recommend shorting BTC or ETH—risk-reward is not great. This is just a reference for potential areas.
