As momentum builds to the downside in the crypto space the likelihood of a flash crash capitulation increases. Not to say it will happen... it is still a highly UN-likely event, but the probabilities increase with downside action like what is currently occurring in crypto. If you a long term holder and NOT buying on margin, buying a hard sell off in flash like fashion can get you some really good prices. Using the market profile you can find some really nice areas to place bids and leave them in case such a fire sale does indeed occur. Here with BTC on coinbase you can see solid areas of support on the volume profile starting with the low of this move.
