Bitcoin’s strong surge to kick off 2020 has caught many traders on the back foot. Case in point: each leg higher in the price of BTC has been marked by dozens of millions of dollars worth of short liquidations on margin trading platforms like BitMEX.While the majority seem to have been caught off guard, one trader called Bitcoin’s emerging uptrend: Financial Survivalism, also known as Sawcruhteez.Just a day after New Year’s Day, the prominent trader claimed that Bitcoin was starting to show signs it was forming a textbook Wyckoff Spring pattern. The pattern, Sawcruhteez suggested, implied BTC was going to hit $9,200 in the middle of January.Possible $BTC fractal that I will be keeping a close eye on. Would line up very nicely with a Wyckoff Spring. pic.twitter.com/qD9MjNRhLT— Financial Survivalism (@Sawcruhteez) January 2, 2020And that it did. By January 17th and 18th, the leading cryptocurrency had passed above the key psychological and technical resistance of $9,000.Now, Sawcruhteez is warning of a potential retracement, which should be a potent caution considering his track record.Related Reading: Analysts Expect “Moonshot” in Ripple’s XRP as Price Retakes $0.30: Here’s WhyBitcoin Could Soon See Retracement, Analysts SuggestToday Sawcruhteez pointed out that for the trading session of Thursday, the ongoing one-day, two-day, and five-day candles are all printing green 9s, according to the Tom Demark Sequential, a time-based indicator that issues 9 and 13 candles at reversal points.The combination of green 9s on three key timeframes, Sawcruhteez wrote, might be a primer for a “correction,” for it would suggest that the short-term bull trend has been thoroughly exhausted.$BTC is on a green 9 on the Daily, 2D and 5D. If this leads to a correction it should be a great opportunity to buy the dip.

Without fiat in the system? How about crashing so that the whole crypto space is essentially wiped out?— Joe007 (I identify as Omura’s seppuku whale) (@J0E007) February 10, 2020He backed this strong assertion by looking to fiat inflows into the crypto market (or lack thereof), noting that the Tether’s flatlining market capitalization is “hard to explain from a position that we’re in the middle of a new bull market” and that Grayscale’s inflow data doesn’t convince him there is enough demand to absorb the mined supply.What Do Bulls Have to Say?Despite all this, many bulls remain resolute in their stance that Bitcoin remains in an uptrend that will not see significant pullbacks, at least for now.Sawcruhteez recently noted that the three-day Ichimoku Cloud for Bitcoin is now “fully bullish,” with prices breaking through the cloud resistance and with the future cloud twisting positive. The indicator signaled a buy at $10,268, suggesting more upside is imminent.
