Maybe it's also because he still believes too much in the coin he's promoting right now so he still ignores research and also trusted projects because he's still very confident about the profits from the promotion of the new coin even though in general any profits are always harder to get for everyone. in conditions like now, especially if the product is still very new, it is definitely necessary to find investors so that product sales can increase.
Do you think that investors are the main point for coin increase? Utopia p2p never had any investors as the project is self-financed, but the coin got +1000% in 24h after some listing on the exchange. After the next listing it didn't get so much, but it doesn't fall much trying to keep more or less stable rate. Seems like another scheme for development.
Yes, I think you are more than right. Investments are undoubtedly a very important way to develop the coin and increase its popularity, but there are also other factors that significantly affect the project and its development.
