It has already affected the price and we've already witnessed the recovery.
Most probably vendors from AlphaBay moved to other marketplaces and
things are back to usual.
Did you mean it affected the price because of the news of the bust and people selling because of it or because of the influx of new coins on the market?
I don't think the sale of the coins themselves would have that much impact on prices since it's an insignificant amount.
Also wouldn't really think that the news itself would have a big impact on the price, but could be wrong about that one.
