It won't be long. I feel that if he is alone, there will be a lot of mess, he really needs a team.
if he serious with this project, and then, yes he need a team. since everything under 1 persons control, for me this project easy to being rugged pull liquidity and run away because his goal already achieved. with current defi scam increased, we must thinking about this possibility before buying any new born coins
Being solo in a project will likely lead to abandonment.
If he got the funds that he needs, very easy to let go of the project.
Unlike, if you have other team members and as much as possible other companies onboard, that will make a lil bit hard to disappear.
But for a project like this, I don't think there are really long-term plans. Just the truth.
