I totally agree with you, my friend. Never do the things you will regret and if you do, never regret. I understand where you're coming from with the hesitation to invest in Bitcoin back then. BTC had a bad reputation and the association with the "dark web" and Ponzi schemes made it hard to trust. But as we both know now, it's a real digital currency with huge potential to replace fiat currencies in the future. It's true that there may be "lost trains" when it comes to Ponzi schemes, but a good project like Bitcoin is always a good investment. It's never too late to start investing and we should never regret not starting sooner.
