This is just a test, I want to build reputation if people start betting, I have good ideas for betting using my youtube channel, trading options bets and randon bets like these one, I am trying things to see if I can make one go foward and start my show.
Do expect people to just trust you out of nowhere. It doesn't work that way. We have got so many scammers on every corner of the web where money is involved. We have seen massive scams get carried out on popular YouTube channels too, so your YouTube channel doesn't count towards your reputation.
Just create a good competitive platform which will leave your customers satisfied and over the years you can get more users. There's no shortcut towards building good reputation.
