Just because other shitcoins are growing doesn't mean wanchain will too. In bull market/trends everything grows and makes it look like you are a genius at picking coins when in reality you are not. That being said, wanchain does have a great team behind it and they already have a working product but wanchain is already expensive so the room for growth might be smaller than other coins.
Of course not only because of that. And apart from what you've fairly mentioned, Wanchain has couple important events in the summer: integration with Ethereum in Wanchain 2.0 and release of multi-coin wallet. So room can be not so small. As for me i'm going to fix some profit on current levels and hold the rest several more months.
