Above all go out there and play. If you do do a 'pump and dump'/Herb format, ask someone about how it works as there are a few nuances on how you can 'bleed out' (not actual blood) and even go up without playing. Those things though really don't matter as much if you just go and get your feet wet first. I did CAX last year as my first Herb format and didn't know what I was doing but learned how to be realistic with it and still have fun and not over-p/lay
