Where do I find cheap bitcoins? Most people are selling it super overpriced much more than the market value

Market value is what people are willing to pay for it. You end up paying a hefty premium when using PayPal, because sellers (like I used to be), have to compensate for the fact that we deal with scammers. Its more or less a convenience premium, and is most definitely "market value." If you don't want to pay it, use a money transfer, or another method of transferring cash.
fine paypal is bad. then could you please advise while electronic payment is good ?
there is an expectant community waiting to buy bitcoins
the exchanges are broken
there is money to be made IF the payment hurdle is crossed
NOT all buyers are scammers
I am NOT a scammer
It makes absolutely no difference that you aren't a scammer. The fact of the matter is that this payment type is used by scammers.
Although it may seem old-fashoned, you do a wire transfer. The idea of exchanges isn't bad, its that everybody gave one a monopoly. Use alternates. There are entire threads here dedicated to various options.
