Your stats are misleading, if you are going to update every market price as exchanges telling you, there will be many new comers getting scammed just because they thought some coin was legit or they would just invest thinking exchanges are providing the real market stats for a lot of coins.
I'd not list any coin if it's not listed on at least five major exchanges and if it has low volume.
Thanx for your feedback! Soon we will add new filter "Exchange count". So it will be possible to see only currencies added to many exchanges.
We have added 2 new big exchanges to our listing:
1.
Huobi - 84 markets.
2.
Liqui - 174 markets.
