This is your first investment? Well shit, you really picked a good one. My advice: hold on to your shares for as long as is necessary for your financial goals. If you hold for a year or more, you pay much less taxes on your sale when do you decide to sell. And with this company, a year from now could be a huge difference from where it is now, so it's definitely something to consider.
Other than that, grab a seat, get your popcorn ready, and enjoy the fireworks!
