Kava is a project that runs IEO on the binance launchpad, maybe you already know the price for public sales? I think it's too risky because prices have gone up 150% more, this might make sense because some IEOs in binance always experience the same thing at the first time but this situation is usually not too long and slowly the price drops, maybe it's just for consideration you.

I don't know enough about Temtum so I can't give anything for you to consider.
