Crypto caps are calculated by multiplying the price by the potentially circulating supply. In most cases there isn't enough liquidity to accommodate the biggest holders, so there isn't much actual circulation happening. If there was enough liquidity to unload this dormant supply, then the actual coin prices would be much lower. Bitcoin doesn't really have this problem - the trading volumes are much higher and there is a healthy OTC market for huge trades.
