What's stopping you from using cryptopia or coinexchange?
Binance is 111 million volume. Cryptopia + coinexchange is 21 million put together.
Binance has a good business model. They have a crypto that pays dividends.
Both Cryptopia + coinexchange have been around for a while - not sure of the exact dates but i don't think they are going anywhere...
I got my XBC from Cryptopia and Coinexchange only. I never used Poloniex.
Cryptopia is the best centralized exchange that I know. Their growth has been tremendous in the last months.
However I am looking forward very much towards permissionless decentralized exchanges, which I believe will begin to flourish in 2018 and allow for more flexibility and freedom.
