1) Do you think about this news will happen ?
Eventually it will but we need a push and more advertising to bitcoin for PayPal to knows the demand of its clients.
2) Do you think paypal may accept bitcoin in next years (3-7) or it is impossible ?
Thats is precisely possible but a 3 years from now is too early a 5-7 years might be the date.
3) Do you think bitcoin will be better than paypal ? when will happen ?
You mean usd than bitcoin, if yes then Im sure with that. Bitcoin is way more better than a fiat currency that is controlled by corrupt system.
4) which better for now PP or BTC ?
I do use both but minimally on PayPal, Im more of a bitcoin user now. Im more feel freedom using cryptocurrency than a much detailed transaction with PayPal that must be legally binding.
