Anyone know how or why certain exchanges only choose to carry certain coins? An exchange like coinbase only offers BTC, LTC and ETH. I don't even see the point of trading there.
They must agree with token developers. And infrustructure of exchange must support that token. It is Not so easy for both sides.
I do not think that this is the problem from that side or any issue is like that but they find only these coins as working better for them and fr them these coins are enough that is why they are not adding the other coming tokens and altcoins to them. I think that is in their rules and maybe if they find beneficial then they add any of the best coin.
