As of now, there is no direct way to buy Bitcoin with PayPal in the USA. However, there are a few indirect ways that can be used.
The most common method is to use an exchange that accepts both PayPal and Bitcoin. The most popular exchanges that fit this bill are VirWox, Paxful, and eToro.
These platforms will allow you to buy Second Life Lindens (SLL) with PayPal and then trade your SLL for Bitcoin.
Another option is to find a person who is willing to trade Bitcoin for PayPal on a peer-to-peer platform such as LocalBitcoins or Paxful. There, you can find many offers from people who are willing to trade Bitcoin for PayPal.
Keep in mind that you will have to pay a higher price since sellers are taking on the risk of buyers reversing the payment.
The last option is to use a Bitcoin ATM. While there are not many of these around, they do exist. To find one near you, check out Coin ATM Radar.
Once you find an ATM, simply deposit cash into the machine and get Bitcoin in return. This process will usually have fees associated with it.
So, while there is no direct way to buy Bitcoin with PayPal in the USA, there are a few indirect methods that can be used. Just be sure to do your research before using any of these methods, as they all come with their own set of risks and limitations.
