It depends. There's just so much difference in 2017 and 2020 since 2020 was the year where businesses are starting to recognize and implementing Bitcoin. 2017 was the year of the hype (remember ICO and Bitconnect?) and doesn't really have that strong support which is why Bitcoin dump so hard. 2020 is the year where people see the value of cryptocurrency. Paypal and other many institution is starting to make a move.
IMO, the bull run has just started. And the rally will happen in 2021 and not next month. PayPal is slowly removing the excess supply from the cryptocurrency market. And the impact will start to appear within the next 3-4 months. Now the spike is purely due to the news of adoption by PayPal. But once the supply crunch sets in, the proper rally will begin. And that is going to be huge.
