Bitcoin Holders are stronger than Altcoin Holders, that's what I see, 2 million tokens never come out of Sathosi wallet and Whales in the top 10 list only issued Bitcoin in a few months, this is what makes Bitcoin price go up, because of the Number of Holders and they don't sell like altcoins do.
Altcoin's market cap will increase if new Altcoins have Holders like BTC, thus new investors will buy at high prices and continue like that.
