Not in a way that would lead them to be included by CoinMarketCap. Let's drop everything but the top 100: how long before the sum of the market cap of those 99 other coins surpasses that of BTC? If you look at the general trend of things, not too long. And who cares? It is symbolic more than anything -- the rise of altcoins into their own (most of them won't make it ofc).
You'd be surprised.
But yeah, lets take "top" altcoins. ETH has a 72 million premine. Remove the coins that are not in circulation and were created out of thin air and you'll get a market cap that is closer to reality and equal to $92 billion instead of $246 billion. A lot of others are the same too, BNB, XRP, USDT,...
Or take shitforkcoins like BCH, majority of bitcoiners ignore it while it still says circulating supply of 18.7 million while the real circulating supply is far less since when they copied bitcoin the supply was already a little less than 18 million.
It is extremely easy to create billion dollar market capitalization out of thin air with zero cost
Well, that's how Bitcoin got started.
From block 1 when circulating supply was zero anyone could mine bitcoin and get the reward on an equal playing field without anyone having any advantage. To this day that is the same, anyone can mine bitcoin and get the reward. So every single satoshi from bitcoin's circulating supply hence its total value was
.
In comparison a premined altcoin or a token creates a huge supply (eg. 72 million coins) literary out of thin air at the very start and the coins are owned by the creator of the coin and others can not get those coins unless they pay real money to purchase them.
