Ok can anyone tell me about the money situation
It's complicated and changes a lot. There are more than a few threads that have discussed this issue into the ground and you would probably be better off reading them than having all the diverse opinions crop up again here.
However, very short answer: Bring in as much of your currency as you can to change on the black market here. I'm really not sure about currencies other than the dollar vs peso because that's what matters to me at the moment. Certainly I would lose around 30% of my money converting into pesos if I just extracted money from the ATM.

& how to avoid getting counterfit notes passed onto you in your daily transactions?
Counterfeit notes can be a problem here. You have to examine every one of them to be certain. Counterfeits are usually easy to spot if you know what to look for. You may have to ask someone to show you a counterfeit to understand what to look for, but it could indeed be a problem.
I have changed money on Florida street many times and have never either gotten a counterfeit, or they were so good that even store owners can't tell the difference. Others have posted that it's a huge risk to change money down there.
I mention Florida because it's the easiest, though also the lowest-paying, way to find access to convert dollars for pesos on the black market for people with no contacts.
Be here for awhile and you will begin to make contacts.
Depending on how long you want to stay here for, I think a bigger problem you may have will be related to renting long term. Short term is more expensive just comparing the price of rent, but long term is extremely difficult, and I would say nearly impossible without contacts, as owners here (maybe 95%?) require a guarantee against the property and rent. The guarantee is in the form of the deed of an existing property here, usually (but not always) restricted to Capital Federal.
