Congrats! Now please, don't be me.
You made a decision and invested, that's a first step. If You're extremely lucky, You picked a coin that'll simply grow and won't have big corrections or prolonged periods with price crawling or slowly declining. Sadly, or maybe naturally, most of coins behave not exactly how our greedy minds want them to.
Patience and learning to understand trends on Your own. Hella difficult, but for me it already pays off and I know soooo little.
Emotions make life colorful, don't they? That's true, but it looks like it doesn't apply to investing. Investing based on emotions is not colorful, more monochromatic - all soon becomes bloody red :-D
