It's a big step for Cryptocurrency and Bitcoin the gap is now going to be wide for altcoins that have no usage to the community, every time there is adoption for the top coins in the market, new altcoins will have a hard time pushing for volume and price.
It is better to invest in the top coins in the market and the majority of your portfolios should be in the top coins in the market, only allocate a small portion if you see a good coin, because it will take some time before they reach their potential.
yes, now the adoption is clearly increasing on the top coins, and for new coins it will be difficult to develop if a large adoption occurs on the top coins in the market.
New coins actually have a role to play in increasing trade but with a bit of renewal and a weak market it certainly won't last long.
