We all find it hard to move on from a project that did incredibly well, many are still buying Shiba inu today because they believe it can do another 1000% gain in future but the reality is I don't see how anymore, don't get me wrong, Shiba will still be a profitable investment but what I have learnt so far about making the biggest gain in crypto is becoming one of the earliest investors, before the project get popular you should be in, that's when you should be expecting 100x - 300x.
Not all "earliest investors" get lucky and profitable. Some of them don't even truly understand what the project they're buying into is all about and that tends to make them sell off in panic once price dips. We saw that with Bitcoin as many early adopters still rue their panic sales till date. You can verify this with any early Bitcoin adopter you know.
As for your analysis of Shiba Inu, I believe it still has enough room to breathe and move upward in price.But it'll be a short upward. The number of people invested in it is too much while there is nothing to keep them stay or 'hodl' Shiba. They'll cash out their bag the first chance which in turn makes any movement of price going upward will be very short and unstable.
