1) Do you care whether the influencer is playing with their own money? ("fake balance" x "real balance")
Yes I do because he is fooling his audience with the fake balance, those users who enter to the stream and see a balance over a million they think that's real money, and it's just a lie.
2) As a viewer would you appreciate if the influencer were fully transparent? (showing withdrawals, deposits, playing under same conditions as every regular casino user, etc.)
That would be nice but it will never happen because they got paid for the stream, not for their wager or bets, their goal is to give a nice show and if they withdraw $10k or $100k that money doesn't come from the bets.
3) Is the amount of money the infulencer plays with important to you? ($500 x $50k)
yes, while the bigger the amount better the stream, isn't the same to see a $1k win than see a $1M win. The $1k win doesn't make me feel anything at all.
4) Considering we have two streamers, one with $500 playing with a "real balance" and being transparent about everything without faking his emotions, and another with $50k playing with a "fake balance" and not being fully transparent thus his emotions are not real either - who would win your favor? (I've only outlined the basic differences here but if you have anything that's important to you in choosing a streamer I'd be extremely glad to hear about it - it would really help me a lot!)
I would say the one with the real balance, even if it's a low amount, the fact that he is really gambling and risking makes it better.
