Probably it is. Since PayPal is a huge network, it could also be influencial to other networks and also people to trust cryptocurrencies. This may then build a rapport with this thing called trust but that does not guarantee things. There's still no assurance that mass adaptation would occur but let's just hope that next year will be something positive for this market.
As what I have read from the article, the implementation would be next year but it did already make an impact because that is quite something unexpected. PayPal is widely being used across countries while Bitcoin still is working with the adaptation.
