Going with your guts with a project that you are looking to invest in is not a very good idea in my opinion. Everyone can have different gut feelings based on circumstances or even what their heart or mind says about something, and that is now how markets should be judged as it can put you at great risk of losing your capital invested in that particular project.
So the best practice is not to follow your gut feeling but does extensive research about the project before you take your final decision of whether you want to invest in it or not, and your research must involve every possible aspect that can be an indication of a project's potential in the future.
At least for OP, he has explained that it's not just pure guts but he's also doing research and reads a lot of opinions so, it's not just really all about his guts alone.
And that comment of his is just posted above yours which basically is a good thing that he has explained because many of us thought about it that pure gut isn't good idea at all.
I just read his reply above where he explained what he means by following his guts, so it's right that he actually doesn't mean that he just follows his guts without any research or analysis, and I think that's how everyone does it, they check a project, do their research and check everything up, and by the end, if they still are not certain about it, they may skip it even if there is nothing wrong by looking at it.
How gut feelings can sometimes save us from very big losses, even if it can cost us some great opportunities too but it is always better to be on the safer side. At the end of the day, not getting anything by not losing anything is better than not getting anything by losing something.
