It was showing high yield in binance so has a risk but i think my luck is not so good. Is there any other network you trust on? In last 2 hours it went upto -$270.
To bet with 50k $ (despite the statut of the coin itself), i think it's normal to have a loss of 200$ by a small price decrease. If you have won 200$ in 48 hours, would you get the same doubts after you loss?
Don't expect veteran members to give you investment advice about which coin you should give it a try, unless for bitcoin or ethereum. Personally, i don't advice you to invest money that you can't afford to lose and not to trust almost all the ERC20 tokens, they are all hyped.
I support the opinion of Jerome that you are getting a high risk by investing big money in unknown projects followed by hype.
