I agree that it is necessary to have experience to choose a good project for investment. Newbies very often invest money in scams.

Very often scams have a lot of advertising and active promotion. That is why a lot of people invest money in scams.

Usually a lot of projects have a big advertising campain during the stage of IEO but after IEO when they collected money, they stop advertising.

Yes it is! But the EDC Blockchain is still struggling to attract new users, and to mine they are doing great!

I think that team of EDC pays a lot of money for the promotion and advertising of the ecosystem.
