Do you think that buying slots on this kind big websites is a good idea? Maybe much better will be spend this money on ads at Social networks?
Since your project has to do with crypto buying ad slots and also try to list your site on coinmarketcap will be the best suggestion cause some crypto investors easily trust project listed on capitalmarket and you can also offer some genuine airdrop to attract new users either and also be more relevant on this forum by creating an ANN thread.
