Your data about BTC exchanges volume ranking is wrong. For you are counting volumes of Net Settlement and Future Trading for bitFlyer. As you can see the correct data on another web site for Japanese,
https://jpbitcoin.com/markets, the volume of bitFlyer is 2nd in Japan, not so big as your data shows. Please fix it by removing the volumes.
We've just fed their volume from the API Bitflyer providing. we'll try to check the issue and inquire it to Bitflyer soon as possible. If any correction or changes, let you know here. Thanks for the report!!!
It seems you are using a wrong key, "volume", for volume. "volume_by_product" is the right one. "volume" includes all volumes of BTC-related boards. Sometimes people used your wrong data for pumping/dumping in Japan. It really sucks.

Hello emmettoc again!
We're having claim from Bitflyer. they said that coincheck also contains their margin volume on their ticker feed.
Now, I'll ask about it to several major exchange whether their volume contains only spot or not. ( I guess that every exchange might contain margin also. )
Then I'll revise our rank page data with description. It will take some time...
Thanks..
It seems that they just want to advertise their exchange. The fee for Margin/Future trade there has been zero, so bots can increase the volume as they want just as Chinese exchanges did before. Still useless data. No more comments. Bye.
