When the additional coins be available?
As soon as possible. We apologize for the delays. ETH should be up soon with the other coins following. The 30% bonus will still be applicable for these coins when they come live.
Is the identifyer: 2rRU7XHihAp9M4PZyCn6JuKPP5fv2Tr3JDn1SrtT6A5e on WAVES DEX a scam?
Yes. No tokens are for sale on Waves, just on ico.moneypot.com (where Waves will be accepted soon).
