I bought my first btc by pp, and had no problem, but not everyone is honest.
There is no risk BUYING w/ pp the risk is on the seller.
You were honest but if you hadn't been the seller would have lost the funds and there is nothing he could have done about it.
Technically depending on when the trade was even if you had honest intent you could change your mind now and chargeback the tx and the seller would still lose.
Yes, that's quite right.
Of course, my honesty can only be stated by others, but as far as i can say to those who don't know me, I am an honest person. I wouldn't feel good with my self if I had reversed the transaction. It would be like stealing.
And those less honest ones, are the ones taking down the bitcoins. They don't see it is bad not only for others, but also for them, since also they can be scammed, or each bitcoin they stole lost value.
