If my account is the basis, then I should be already a hero member or a legendary member, right? I just recently came back after several years since I was also busy with my study, and yes, it's true that I have earned a decent amount before and most of those earnings went into a considerable good investment such as my computer which I was using for 5 years now and other needs. Now for the present time I could say I somehow regret it but as I've said it is a considerable good investment for me since I made use of the things I needed back then and should be grateful for that. Additionally, now what I'm really aiming is building for myself and investing while utilizing the resources that I have, because I know crypto or bitcoin is one the things that will greatly contribute me in the future. So, I do hope that I could read some of your suggestions, opinions and gain more knowledge which I literally skipped over the past few years.
Perhaps not on your first question, your account was created way before the Merit system was introduced, if you were a Full or Senior Member on or before the 24th of January 2018, 500 merits should have been added to your account by default for every member who was already here and you your merit is reading 253, I don't think you will be in Hero or Legendary at this point even your activity defined that on your profile.
As far as you used that bitcoin to get to where you are today, there shouldn't be any sort of regrets, it is a sad action done with a good purpose, this is not the time to feel awful, make use of that knowledge and buy back some bitcoin, you will enjoy the boldness of starting over in the future.
