OP, we need to know the name of the coin that existed so successfully without falling for four years. Otherwise, there will already be inconsistencies in your story, and many will simply begin to ignore you as a liar.
I can't hold myself with laugh
It has become a norms here seeing things like this on a regular basis and I don't longer find it surprising again. This thread reminds me of a statement that says "always speak truth so you don't have to remember what you said in the past". One can decide to lie, it's fine but at least it should be convincing enough and well compose so people might probably learn from it. That's what we called fictional stories.
Reading through the Op thread, I actually expected to see the name of Shitcoin he/she invested in for that long time without realizing the mistake despite claiming to be doing research about cryptocurrency in a while. However, the point here is regardless of whether the story is real or fabricated which is most likely, lesson is being learnt and he's open to reality now.
