I don't really like this.
Altcoins are thriving just as before the crash and it gets worst.
With the number of coins slowly losing dominance over time is expected, but, this loss has been quick. What's more, we are likely close to another coin becoming the market leader. Can you imagine that, A banker coin like ripple, and a broken dictator coin like ethereum becoming the peoples choice.
I should never of expected different I guess, most people in this world are dumb arse sheep only care about profits rather than making the financial system better.
This effect is bound to accelerate with the growth of the overall crypto market. The more people buy into Bitcoin, the more people will find interest in altcoins and the larger the potential volume that can trigger growth in altcoins will become. It's a snowball effect.
A question that I find interesting is whether or not Bitcoin will regain dominance massively once the "big crash" comes and useless shitcoins as well as all the ponzis and scams get obliterated.
If a big crash happens. They might just drop off one by one, only to be replaced by more new entrants.
