That's always the case, those who invested earlier can play much with any coins, as we knew that they can sell it out in a bargain price as they acquired those cheap coins and now its bringing them huge profits, we can't change the fact the that's how this business was design, early birds always are the big
gainers there's no exemptions, ether bitcoin or eth and all those coins inside cryptos.
