many but it will make BTC expensive , because total investment / (total supply - total lost forever) is more than total investment/ total supply
this is correct. bitcoin's totally circulation amount is reducing day by day. specially after those so many altcoin projects and their ICO... thousands of BTC still frozen in ICO escrow addresses. thats also a reason of bitcoin price increase.
The reason why the bitcoin circulation is frozen is because many people are holding and waiting of the price to get a $1000 so they start selling, and the constant demand on it drives the price even high and the higher the price the more people greed and hold the bitcoin even more, but we will see a big change in the price when it reaches $1000 or beyond that also.
