Bitcoin has been steadily losing market cap dominance, from 90%+ just two years ago to ~80% today.
When it comes to exchange dominance it's just 66.4%.
This trend will probably continue and in a few years there will be people using cryptocurrencies that do not know what bitcoin is.
That is very interesting. I will assume it is probably true what you say about the 66% bitcoin exchange. There maany altcoins out there and many people looking for profits. It makes sense thst the % for altcoins is high. I wonder when it will hit 50/50 ?
