A lot depends on who promotes memecoin, how well the advertising company is built. After all, the crypto community needs not only to be involved in the project, but also to organize it in order to increase the liquidity of the coin.
Look at the usage of the coin, rather than looking at who is promoting it. As we have seen earlier, people like John McAfee promotes shitcoins in return for a payment. So investing in a coin, solely because some celebrity is promoting it will be a wrong strategy to follow. If you want to invest in a new coin, look for uniqueness in the white paper and check the rate of adoption for the last 2-3 months. And if it is listed in some of the major exchanges such as Binance, carefully analyze the trade volumes for at least one month.
