We always make this suggestion and warning that before you make an investment on anything first engage in making research about them, first the exchange you said you make use is not that reputable, upon that, using a reputable exchange is never a guarantee assurance for not loosing your coin because they will state it on their policy for you s caution, they will not be held responsible for any trade or investment you made with anyone, they are only promoting the coin or token, you're only doing what you should have done in the first place at the last stage.
