Yesterday bitcoin swept all other major coins and has shown zero sign of slowing down. However, there are only so much money to go around.
I think the $18k target could potentially be reached later today or tomorrow. The weekend could be a period of confusion. Come Monday, the big crash many portended will be real. Altcoins may also be implicated. Seeing this last extension has been so dramatic, a fall to $9k is expected.

Alts also are risky these days. But, positively, after crash they will recover faster than btc
