Ive been using Probo app for a while now and I really like it. About the max amnt you can withdraw from Probo - I’ve withdrawn up to 25k at once without any problems. Probo keeps your winnings in something called a Winnings Account. This is where the money goes when your trades are right. You can either use this money to make more trades or withdraw it directly to your bank account. Just make sure your KYC is complete and your account is linked. I’ve never faced any issues with Probo. My money has always come on time, and the app is very clear about everything. If you follow sports (Im a cricket person) Probo is a great way to use that knowledge in a fun way. I really enjoy using it, and the withdrawal process is smooth and safe. So yes Probo is safe and you can withdraw your winnings without any prblems.
