We are on the verge of a new euphoric bull market. Look here: In a bull market everything is positively correlated to BTC, but altcoins grow much faster, so it's better to focus on them.
ZRX has been one of the strongest coins throughout the bear market. It's a protocol for creating decentralised exchanges which is probably one of the greatest problems to be solved in crypto space right now. Binance, Bitfinex and other exchanges had more than 1.5B pure profit each in 2017. ZRX is attacking this space. If they succeed market cap can be much higher than of all of the centralised exchanges combined. Great team solving real problems. What can go wrong?
Lots of possible catalysts. Joining Coinbase, Ethfinex potential success and much much more.
My thesis is that BTC will go to the moon and ZRX will be one of the leaders of the coming bull market.
