Theoretically, BTC is just a rebound if it doesn't break through 100k, but if it breaks 100k, it could also be a false breakout, forming a triple top, entering a bear market in 2020.

So it is recommended to try a small position at 120k; go all in at 150k; wait for a confirmation of a crazy bull at 200k to increase your position with loans; sell your house and car at 300k for rolling operations!

This is the trading technique pioneered by the master Livermore - the inverted pyramid method for increasing positions. Exclusive secret, do not share.
