How many of the coins in this list are heavily premined, and the high marketcap/attack-price ratio is only related to the big amount of coins hold by the creators?

Is it possibly to see other indicators like daily volume? (that can also be manipulated ...)

Interesting site. Only thing I would change would be to find the attack cost based on block time. Ethereum has a block time of 15 seconds whereas Bitcoin has a block time of 10 minutes. This changes the amount of damage that can be done in a given amount of time.

I welcome pull requests [0]! :)

Nice! I didn't realize you were on HN, I've sent your site to friends before. I'm curious -- has your traffic increased or decreased lately (due to the bust)? Do you track your traffic or graph it at all?

I track it via Google Analytics -> here's a screenshot of the last few months [0]. Traffic has been pretty steady over time with a few spikes from Hacker News or Twitter mentions. I believe the most recent spike in traffic is related to the 51% attack against Vertcoin [1].

How come they don't list Monero (XMR)?

Oops - good catch. Monero moved to a new mining algorithm (cryptonightv8), and crypto51 was using an old hardcoded list of NiceHash supported algorithms. I just updated the site to use the NiceHash API to keep this list up to date [0].
