It is rightly noticed, sometimes it happens that the project is interesting only to small investors due to its specificity.
How can the specificity features of the project influence the investors decision? All an investor needs is a profit. Of course, some people may have ideological principles, but in general an investor can invest in anything if it can make a profit.
I agree with you. An investor can invest in anything just to make a profit. The main task of the investor is profit, and it is for these criteria that they select projects.
