you can buy Bitcoin Mining Hardware tools throw paypal but why cant buy bitcoin by paypal
is this logical

?
Paypal is a payment method and as much as you can pay someone or a company via paypal to purchase a mining gadget is the same way you can pay someone on localbotcoin or even use paxfu to purchase bitcoin via paypal. Even on this forum, there are so many people who can send you bitcoins in exchange via payment using paypal. So, I do not understand the basis of your question and please you guys should make use of the internet rather than posting shitty things like this here on this forum (no offence)
