The Moon carl has also said at one of his speeches at a gathering that Bitcoin would never drop below $10k, mostly when these people say such thing it always happens lol. This is what I hate about them without any serious re they will be just repeating bitcoin won't go below this, below that or Bitcoin is going to pump, going to moon and other non sense.
Still $18k is very crucial, but I feel $16k would be a level bitcoin is going to test.
That $16k level is looking much more likely after the last few days than it was prior...
