If you are familiar with Wyckoff you want to look for your spring below axis (below 25-30 level even better).
This is just one piece.
The current situation shows BTC playing around this 20K ish level. It looks like they are taking profit. Its still an uptrend so I am still looking for re-accumulation. Because price is pretty high I want to see what happens here and how the market handles 19-20K in addition to all the US politics,Holiday season, financial news ETC.
Not a bad tactic to keep the risk light when there is all this push and pull going on everywhere.
But if you are going for it… BUY LOW/SELL HIGH!
