I think there are so many great projects out there it's hard to choose. I always try and look at what I think is undervalued relative to the rest of the market.
A lot of the other "blue chip" cryptocurrencies, like Ripple, IOTA, Cardano, EOS and others have gone up significantly. NEO is the only one that's been quite flat for a few months, and especially GAS. The charts look so bullish though, I think something very big is just around the corner for NEO.
Yeah, even steem is going up in the last couple of days and gaining the value it deserves! In the other hand, NEO seems forgotten, like ETH some months ago. I'm also going to fill up my tank with some GAS, thanks for the suggestion!
