I have my own sob story in regards to Bitcoin, from the early days. But, I cannot have regrets, I cannot dwell on the what ifs. I made mistakes and have missed opportunities, but there will be other great opportunities in the future.
Those who have heard about bitcoin a few years ago but was skeptical really had some regrets. They did not believe until they have witnessed their own friend really started earning a lot because of bitcoin. But that doesn't mean it's too late. Those who believed before may be just luckier but still it's not too late. Maybe it was just not the right timing. Still, you're lucky enough to have known about bitcoin. So now that you already know, don't let the opportunity pass.
