If you look at the top 20 exchanges in coinmarcetcap , we see that half of them created in 2018. That is the year the charity was able to get one of the best. But now, the competition between platforms much more so to be among the best.
It's true, the competition in the crypto world is high now, we need a strong marketing plan.
By far, the most important thing for a new project, if the marketing plan is absent, we can assume that the project will not happen and will not collect even coftcap. Marketing and advertising now ranks first, the very high competition in the market.
Marketing of course very important, but I think in the first place is the product itself, as a bad product even with the best marketing plan no one will use, and Vice versa with excellent product and an average marketing project will flourish.
