1. PayPal is risky enough for first time traders and charge backs could be a big headache and an extremely painful experience for such newbies, I'd suggest you to send your money to a friend whom you trust (only if you personally know them as well as have faith that they may never cheat) and ask them to buy you BTC locally. Exchange at their place may have cheaper fees than what you're being suggested. I'd ask a question someone already asked - Why only PayPal?

Shdvb's thread, this guy is trustworthy enough if you wish to buy BTC, the only problem is, he doesn't sell BTC with PayPal, but you can use:
Payoneer
USDT
Bank Of America
If you could manage PayPal, then I guess that purchasing USDT won't be a big deal for you as there are e-currency exchangers that do such trades, but it's more riskier than PayPal alone. So, if you could manage MoneyGram, I believe that buying BTC won't be a big problem.
