Many of the projects in the top 10 use various techniques to suppress circulating coin supply (e.g. masternodes, coins locked away by developers). These coins are not excluded when calculating marketcap and so a spurious value is assigned to the whole blockchain.

That is also completely ignoring that there is clearly manipulation involved in the marketcaps of many projects, particularly those that exist only as an ERC20 token and/or whitepaper. It's easy to pump the price if you secretly control a large number of the tokens and can suppress selling.

Monero does not use any of these tools and so will have to do it the old fashioned way: i.e. introducing a real, functioning product that actually does something that is valued by users.
