What do you think about SEMUX - better hold it or sell?
I don't think this coin is something that's worth to put your time, money and effort but who knows if this coin does have really the potential.
Try to read it's whitepaper, road map and all the things that is related to that alt coin. Just like UNO no one is expecting that there will be a pump scenario of it and it can possibly happen to it.
But if you believe with this alt coin just hold it, otherwise just sell it when you've got enough profit.
