in theory, it should be (Bitcoin up to $ 20k due to the effect of this positive news), Bitcoin is a decentralized coin (price changes occur due to the volume of demand that occurs in the market) if the Bitcoin price hasn't reached $ 20k it means the demand level hasn't "exploded". I think we better not force Bitcoin to be at the price $ 20k, let the price move to $ 20k naturally. I think till the end of the year Bitcoin won't reach $ 20k, most likely next year (Bitcoin up to $ 20k and maybe more)..
Not necessarily,,, PayPal is only rolling it out in stages, and everyone has been capped at the moment. I think a lot of PayPal users who would like to have BTC already have it, this is just mainly targeting those who didn't feel bothered enough to go out of PayPal to get their own BTC. Still, long-term adoption effects can be expected.
