GAS is still one of the most undervalued coins. You see, I expect NEO to be huge by the end of 2018/2019, but it has experienced a big rise in 2017. Not the same for GAS, but notice one will need GAS for NEO transactions.
The charts shows a bullish trend on all levels but level 4. All of them have shown a BUY signal recently. I think it's still a good time to enter GAS. Available at Binance.
