I find it baffling that Viffer keeps arguing with the same thing over and over again "What if I bet with someone who can't pay to me, what then?". This is absolutely irrelevant to the situation, I almost can't fathom how bad this argument is and how someone (presumably) smart person can keep saying this
Betting hundreds of thoudands of dollars without contract is quite risky, as there is always a chance someone will freeroll you. You never know who ends up being a scammer, I guess Viffer's reputation was good enough to bet without written contract
(although verbal contract is just as binding as written, only harder to prove) but now it really looks like he is going the same route as Mr. Rheem.
He is also avoiding direct questions which makes his actions look super shady, like 1. Are you going to honor the bet if they finish the challenge or settle? 2. Is the bet with ZeeJustin also determining the outcome of the bet you have with Jungle?
