Btc has run too far too quickly possibly due to manipulation by hedge funds. But it wont crash too hard I think. By guess is undervalued alts will rally hard now. Just a guess
That is why I believe that many of the altcoins already had pumped prices through this week. The ups and downs are being adjusted according to the prices of bitcoin. I clearly saw how the alts went down when the bitcoin was going down since two days. Now bitcoin has got its dominance again and it is on the verge of going back to 11K today or may be more who knows really! So alt coins will follow the same in the future to come.
But it wont crash too hard I think
Hopefully we don't see that one and I don't loose my investment in the meantime. Lolz.
