I don't know why nobody in the comments made advised you to get focused on building your account. You have less than 70 activities which means you just about three months in your account and you are looking into jumping in for money. There are accounts older than you that have not got into such benefit if I may say. So focus on your account and build your knowledge. For the information you need to hear, member accounts these days hardly get such opening especially in btc signature.

My advise for you is,
how about working to upgrade into your next level?

Bounties are no guarantee that you won't waste your time because of scam.
It is adventure depending on luck.
There are few reputable managers , yet not a guarantee you will get the project in an exchange.
