XVG is not slow and steady, it is more pump and dump. The best coins for 2018 are the other privacy ones like XSPEC and Deeponion. Otherwise for slow and steady go for one of the better known coins like NEO which will definitely rise in 2018
To be honest the way XSPEC keep pushed hard on this forum make me think not once but twice before even touch it , Anyway I am staying away from xspec , There is other project that are really good Tron , XLM , POWR and the list go on .
