BTCUSD is possibly showing us a new Head and Shoulders Top on the Daily chart here. Yellow trendline is the neckline/support. Certainly not the cleanest Head and Shoulders so it may be nothing. But with this thesis in mind, BTC seems to be printing the second breakdown attempt below the neckline. If this pattern does see follow through to the downside then a 50% pullback in cryptocurrency would not be out of the cards.
