I made a 100 $ contract, it seems is OK, so i will wait and try a large amount later
OP... did you read the replies on this thread? everyone was against the platform and they all had good reasons for it.
In addition, even if this 100 bucks contract went fine, it doesn't mean you can trust the platform specially with a much larger amount as it could be a bait. Since we're talking about large amounts, the owner/scammer could even decide it's a good amount to run away and move to a new domain.
Sadly he reached out to the community for helpful advice, but in the end, he ignored it all and made his own decision. After all, for newbies, anyone's advice won't win over their greed. Let him try with it and get results with it, and he will understand what people have told him.
Newbies need lessons and experience, and all of that should be bought with money. That way, it really matters to them, free advice will never be worth anything until they pay for the lessons.
