The best way to be involved with Bitcoin is to set up a bitcoin wallet.
I use Coinbase.
Very easy.

I made a very small investment into Bitcoin 2 years ago.
Have bought plane tickets directly with Bitcoin.
You can spend directly out of your Bitcoin wallet at Coinbase.
Bitcoin will be very established when it is used for commerce by regular folks.
