BTC as we have seen has huge potent if closes above 23419 and sustains, sustaining can bring lots of changes and can go upto 27K in a day considering there is no prior resistance. But i see a rounded retracement till 17573 and spring may happen before any prior movement as it cannot sustain 22000. So one can short from 22000 till 21500 and 20820 but eitherways holding can be done again at 18500 levels! Though make sure weekly chart has 300 SMA res and it may bounce back to 35k prior
