But look at it in positive way, if that happens bitcoin price will go down and you will be able to buy cheaper bitcoins and sell them later for higher price
some says satoshi nakamoto is dead so , he cant never sell his own bitcoin and the whales are only holding a large amount of bitcoins but i guess they wont either sell it because if they do , it will greatly affect the market and will ruined the bitcoins value. but i dont believe that bitcoin will be sold out because there are still millions of it that arent mined yet and the others are always circulating from one person to another.
