We are seeing BTC have nearly 52 to 55% dominance in the whole crypto market but while taking these figure about cryptomarket we also have to keep watch on marketcap of cryptocurrencies.
the whole point is that you should not look at market cap of cryptocurrencies because it not only means nothing but also it is meaningless when one is higher than another.
for example you can create a new coin by copying the code of some other coin, from bitcoin to any other one. then change their supply to 100 trillion. then after releasing it, you sell 0.01 of your coin on an exchange for $1. now your market cap is 10000 trillion dollars.
do you see how fake it is?
