Re: Proposal to Address Dormant Bitcoin:Recycling Lost Coins into the Mining Process
What would happen if the owners recovered it's private key now or in the next years and suddenly woke up and moved some of its coins? 
Perhaps it would be Satoshi?
Perhaps you're asking if it will have an effect on the price. Perhaps it would be Satoshi?100,000BTC is a huge chunk of the total 24hour trading volume. If a previously dormant wallet became active and sent them to an exchange address, it could influence the market slightly. If it was traded on an exchange and not done OTC it will also have an effect on the market.
But the influence will be short-lived and likely have a less than 1% impact on the price
