Bitcoin-Don't try to catch a falling knife, sell rallies instead

Two days ago I warned that Bitcoin could fall and since then, the price has lost more than 20%.
After such a dive is normal to expect a correction and this, indeed, is very probable.
However, if you are a short-term trader and you are not a buy-and-hold one, trading against such a strong move is extremely dangerous.
Considering the importance of the break after more than 4 months of consolidation the safest way to trade is to sell rallies.
At this moment 18k-18.5k represents a strong ceiling and in this zone (if is reached) traders should look for selling opportunities.
In my opinion, Bitcoin has not reached the bottom, and a new wave of selling will follow an eventual correction.
