But as I said you don't have to believe me as time passes we will prove our authenticity ourselves
Do you know how easy it is to prove your authenticity if you really want and pretty fast?
You claim you are offering a bounty worth 10 BTC, you could start by signing a message from an address that has 10 BTC and then find an escrow or multiple ones that will hold that sum, easy as pie, can be done by tomorrow morning.
With our bot you only have some funds in your exchange account and connect the API key.
Leave the rest to us. although we cannot access customers funds we still make a profit in
your account.
Yeah right, so what would that API do?

I wonder how this scam will go from this, it's obvious there are no 3 companies, 10 BTC, and so on and on, so my bet is on a one-page WordPress website where you can buy a bronze, silver gold package that promises you 300% APY. I don't see anything more elaborate coming from OP, despite his claims about API keys and trades and whatever.
There is
one on freelancer, which does have a few resemblances.
