Look at the supply first no matter what if the supply it low and the price is also low invest in and hold for atleast 6 months. Now I'm not talking about coins listed on yobit but the top 50 coin if you find any such coin invest in it , one such coin is xvg or even trx.

Secondly look for the number of exchanges it is listed on if it is listed on 1-2 major exchanges invest in it because most likely it would expand and get listed on other major exchanges , but keep in mind they need to have active team and developers.
