as for exchange - Binance, as for exchangers - changenow.
I'm always recommending to search at bestchange, at first. to look at the rates, to read reviews
I also love the same exchange as you like mate.
Always I do the conversion with this exchange since it has most of the altcoins pairs in this exchange.
Sometime people doesn't like this Binance exchange since it is a centralised exchange when there are many decentralized exchanges available...
