Im not sure wether he is affiliated with Duelbits or not ( I think he probably is ) but here is the tldr version in case if you are still confuse

@Botairtx won the challenge of being the first player to hit 10,000x multiplier on plinko thus he gets $10,000 from Duelbits. At the same time, @MelloGambles claimed that he was the one that hit it first but Duelbits removed his bet.

After discussing through discord between those two, @Botairtx decided to send the $10,000 to @MelloGambles as it seems that he is the rightful winner ( there isnt seems to be additional information on how he decided to get to this conclusion ) thus also asking Duelbits to clarify what exactly happened
