The best way to invest in Bitcoin would be by Exchange legal in your state to operate. Or using cash app PayPal or venmo. Cash app allows you to hold your Bitcoin, venmo I don't know and PayPal does not. The most important thing you need to do is to do your research first, and don't allow other people to tell you what to do with your money because everybody has their own risk level. Which is very important to assess before you invest.
