Coinmarketcap is a juggernaut. Everyone I know uses CMC to check prices and coinmarketcap is considered the best place to have your project listed. I really do hope another website dethrones their spot. CMC has been involved in many shady tactis and profiting off insider knowledge. I've seen a few scam ICOs advertised on their website as well.
That is very unlikely unless it's smarter. Everybody wants something free and valuable. Few people spend the money to pay for unwanted items. And they just love to benefit. It will be hard for us. The replacement is not good at all.
