New projects should invest more on the project itself and make it more valuable, the next option is to have a private sale so you can have the funds for more improvements and advertisement, marketing will play a bigger role for this project so make sure to prioritize this as well or else no one will invest with you.
Also one of the big factors is where to use the token like it can be exchanged for some good cosmetic items in some online game or anything like that, in order for the token to liquidate and raise its value. If it has no value, then no one will ever gonna take a risk to buy it even if the price is low and it will be just like the other tokens in our wallets that have been there for years and remain as nothing but some trash tokens that have no value at all. It's hard to promote such coins this time because most investors already get their share of losses from scams and fake projects.
