You're just one among thousands, including myself, who have regrets not buying right away and who have been taught not to react immediately.
But these are not necessarily faults. One who has heard of Bitcoin for the first time would normally hesitate and take time understanding it. You don't just hop right into something you don't know without doing research first.
Also, a newbie emotionally reacting to the market and making decisions based on it isn't surprising. That's why they're called newbies. But that's how lessons are learned, diamond hands are made. The problem is when you're not a newbie anymore and you still panic sell.
