All you all have done so far is throw blind accusations at Maria without much more than scuttlebutt and rumors.
This "trust no one" mantra has gotten a little to extreme.
With that said, I'd like more information about the "code" Maria has generously offered us. Would someone who understands programming code please look into that for us?
Don't think you can. It's specific to the trading application.
There's no reason not to give a person the benefit of the doubt... if they're being upfront and transparent.
No one's stopping you from giving Maria the benefit of the doubt despite her unwillingness to answer questions and to explain her previous behaviour.
I'm all for giving someone the benefit of the doubt but of all the situations to be cautious, where bitcoins are involved it's always worth checking every last detail.
Good luck.
