I've known 7 is close to the lucky numbers just like a jackpot in any gamble which labeled to 777.
But anyway there is nothing correlation between the lucky numbers with the crypto success because it's all depends on the demand of the market, as long as the market demand is high, the crypto must be succeed no matter how good the project is, is all about the demand as we could see from any meme tokens which create a massive marketcap. But the susatainity of the coins becomes on the top needs some real good projects.
