First of all you should to do escrow.
Account everyone can check but you should provide an open list of people involved in that.
Newbie rank and self-moderated thread will not help you.. Just saying.
help me how to do that are you ready for a escrow or anyone here to escrow by the way what i have to do for that
I've never done escrow. I recommend you "devthedev" to do it.
Here you can choose someone by yourself:

The easiest way is to write him PM with link to this thread and few words more, for example.. I'm sure that he will explain you that much better then me

I'm here asking for crypto so how it will help me
Do I need to have collateral??
For example,
i send coins to escrow
escrow confirms this
you use your own coins and generate the profit
you send coins + profit to escrow
escrow releases my initial deposit to you and what you sent to him to me.
correct me if i'm wrong
