~~
If your project offers something promising and is built with integrity, it will undoubtedly be judged on its merits.
Let your project speak for you, and let the community evaluate it and decide whether it deserves to be called “mythical” or not.
Your experience and contributions to those early projects are enough for the community to know that you have the necessary experience and skills, regardless of anything else.
If you don't have your previous holdings, you need to build your capital to move forward and pay the project team members who will work with you on the project.
Also, your previous reputation will return over time; you just need to be transparent and offer something worthwhile.
