I am pretty sure that 98% of altcoins will Die anyway. no matter if Bitcoin Price increase to that point or not. Altcoins are going to die. maybe some major altcoins manage to survive. only 1% or 2%. and rest of them will vanish.
and I think Bitcoin will a lot of time to reach $100k. maybe it take 2 to 5 more years. that's my point of view.
