Doesn't matter. 90% of the shitcoins that exist right now will be dead in a few years. They have big ideas or in some cases half baked ideas and most of th will never even come to fruition. It's naive to think that they will.
Bitcoin is the first, has the most devs working on it and is still by far doing the best out of anything else. Saying the "dominance" should be "less than 10% is like throwing a dart with your eyes closed and pretending that you meant for it to land wherever it lands.
What shitcoin are you shilling here? Or should we buy gold? Silver? It's hard to see why you're blindly pulling things out of your ass until we see your true motives.
Edit: Jetcoin. See? Now why didn't you just go and shill your shitcoin? It's just that easy. No need to sling shit at the one true winner.
But the total share of money invested in crypto is now moving towards other coins. Earlier it was completely dominated by bitcoins. Al though, it is not the right parameter to judge bitcoins in comparison to other coins. It might be possible that a lot of people might be investing in these new coins because of false marketing and ignorance. Regarding those stats for how much total money invested in crypto belongs to which coin, I read that on Quora and another blog related to bitcoins. They mentioned that it has reduced from 90% to 45% .
