Nope you can generate 21M in volume just with a single BCH going back and forth 21M times. There's no need for huge stashes. Plus exchanges can always generate volume out of thin air and they don't need to have coins to back it up on paper. Look at OKcoin and whoboi volumes the day the hammer on wash trades came down
1 Coin going back and forth 21 M times? Is that really what is going on? What sucker is that dumb to fall for that kind of bullshit? Are the Koreans on Bithumb really that gullible? They are at least making the amounts vary a little bit? Right? Otherwise it looks like typical Yobit fake volume.
