That's good news but this is only for the top coins in the market, a forward move for Bitcoin and other coins, they've supported, here in our country our local exchanges and payment processing provider can only accept 5 Cryptocurrency.
The top cryptocurrency in the market is now moving to have a big gap over the other coins in the market, I have this feeling that we don't need more coins in the market because of these companies and payment processing provider will only go for the top coins in the market.
3 or 4 years from now we'll seldom see new coin in the market because of the huge gap in the dominance of these top coins.
I believe what you say will happen if you see the current market is too striking difference between altcoin and bitcoin on the market today.
