Holders are making a future for everyone. I am one of those hodlers and hopefully, I can manage to hold until the market gives us a good price. Once thing is certain, if you hold the right coins for the right period of time I think the result will be some profit. You may not believe they can change the world but when it comes to making profits in high percentages, it will be noticed and felt by the world.
I doubt that, If everyone decide to keep holding and there is no demand in the market, nothing would drive the price higher, For every successful market everyone has their part to play from active traders to panic sellers and those whose sell for little profit, but, I doubt strong holders really have any huge impact in the market as they have no influence in the current price of the market.
