47.000 $BTC (+1,3 %)
and 47,000 $BCH (+2,31 %) will land on the Kraken crypto exchange within the next 7-14 days
and are ready for sale.

Or will simply continue to be held.

The Bitcoin (and Bitcoin Cash in the same amount) that @stefan_21 mentioned in his article went to the crypto exchange Kraken and will be paid out to the creditors of Mt.Gox in the next 7-14 days. They can trade them immediately or simply continue to hodl. This was revealed in an official email from Kraken.

What impact will this have on the price?

Probably not directly on the Bitcoin price. Not everyone will sell. Some will hodl and some will exchange Bitcoin Cash for Bitcoin, which could increase demand in the short term. I don't expect an indirect impact on the Bitcoin price either, as it was already known that distribution would start in July and this should therefore already be priced in.

In my opinion, however, Bitcoin Cash could go downhill for the time being.
