It has become clear the big three cryptocurrencies are BTC/ETH/XMR who will join them next? Keep an eye out lads.
don't rule out LTC
likely the best to join THE FOUR
*which would be THE top 5 BTC, ETH, XMR, LTC, XRPPoloniex is XMR and XMR is Poloniex. The reality is XMR would be nothing without Poloniex.
I am willing to have a debate regarding the above.
