Is DX token already in coinmarketcap? I searched for it and I did not find it. If that is really a great token to buy and have already grown more than double in the last 3 months, it should already have been listed in coinmarketcap. A good project takes no time for their token to get listed on coinmarketcap. They know the value of being listed there. Or is it already listed on major exchanges? Does it have a nice volume?
Yes it has a nice volume and listed in some major exchanges, its real name is DxChain Token or you can check it directly here https://coinmarketcap.com/currencies/dxchain-token/
right now it is at rank #119 based on CoinMarketCap.
As I said before, do not let your emotions take control. I participated in a project before and the price went up for over 500%, the project itself has a real use case but no matter how good it is. The price will eventually decline because the market demand is very low. Secure your profit first before deciding anything else, after you secure it no matter how low the price is in the future you do not have to worry about it because you have secured the capital+interest.
