There are a lot of crypto exchanges around the world and some of them have an option to add your token to the exchange. But if I get it right, the token should be ERC-20 compatible, therefore Ethereum-based? But there is one thing I can't understand (not advertising anything):
As an example, Ripple XRP Token - can be found in many exchanges, some exchanges have few currencies, like BTC, ETH, XRP, BCC and that's all, but the other have XRP and hundreds of ERC20 Tokens, Bitfinex for example. The question is - how is it possible if XRP is not Ethereum based? And if't its just a special support for XRP implemented, then why tokens made at Waves Platform (Wagerr, Starta etc) can't be traded at Bitfinex alike exchanges as well?
What am I missing?
