Lol it's just a thinking but the morale is that I have missed the biggest opportunity and I accept that it's a blunder for not participating positively in btc.
Think about this - every day, each person on Earth misses countless of "golden opportunities". Maybe if you left your home 5 minutes earlier, you would have found the love of your life, or if you bought a lottery ticket at the right time, you would have won a jackpot. And if you knew the perfect trades, you could have become a billionaire by trading on any market with high leverage. Bitcoin in early days is just one out of hundreds of thousands of golden opportunities, there's no reason to be sad about missing it, at this point this is just an unnecessary regret. Focus on the future instead.
