Decentralise technologies have problems with users and liquidity. Not many people knows about blockhain and how to use it. That is why advertising for crypto startups is so important.
I think that the hype for cryptocurency has finished. That is why the price of cryptocurrency continue to fall down.
What does advertising mean? Do you think that the cryptocurrency is no longer interesting to anyone? For example, I think that now it is only the beginning of the development of this sphere. And when Bitcoin will cost 100K and Ethereum 5K, many will again want to buy cryptocurrency.
