PayPal should innovate or they will die off, there are many business entities that slammed the bitcoin market for a long time because they knew that if there is a massive adoption in bitcoin then those companies would be history and hence they were forced to adopt or else they will die and we will see many companies like Visa and Mastercard adopting bitcoin so that they could continue their domination in the market.
The corporations pouring in money for only one reason to adopt to stay in the business or book massive profit during the rally.
I am really doubtful about this. PayPal adoption of Bitcoin was more beneficial to Bitcoin. PayPal user base is stagnating, and they were looking at ways to revive it. But in the end, it was Bitcoin which turned out to be the biggest beneficiary. I can divide the corporations to four, based on their approach to Bitcoin:
1. Corporations which are indifferent to Bitcoin: Includes Amazon, Netflix.etc. They don't want to get involved with Bitcoin.
2. Corporations that want to accept Bitcoin payments, but not open to investment in Bitcoin: Includes Microsoft and AT&T. They have included Bitcoin as an option for payments but don't want to take the risk by investing in BTC.
3. Corporations that have invested in Bitcoin: Includes Tesla, Overstock.etc. These companies believe that Bitcoin will give them good returns in the future and therefore they are investing in BTC.
4. Corporations which are against Bitcoin, but want to exploit the cryptocurrency sector for their own benefit: This group includes corporations such as FaceBook. They want to steal the technology from Bitcoin, and come up with their own shitcoin.
