Forget about that dump, whoever dump failed on his mission to cause panic.
Bitcoin seems to be back again, reached $8200 as I am writing this post, so it looks like we are into a new high for this year.
I am not certain how that sell order came through until we have a detailed media coverage regarding that, if it was a major sell order it would trigger a panic and people will book their profit looking to enter once again when the market retracts but that scenario did not happen and it might be a accidental sell order that crashed the market for a moment and the market started rising again, how long the market rally continues is to be seen.
