As part of 226 slides presented to the SEC on our ETF filing, we did a first-of-its-kind analysis of *order book data* from all 81 exchanges reporting >$1M in BTC volume on CMC.
TLDR: 95% of reported volume is fake but LOTS of good news!
A. 95% of reported BTC spot volume is fake
B. Likely motive is listing fees (can be $1-3M)
C. Real daily spot volume is ~$270M
D. 10 exchanges make up almost all real trading
E. Most of the 10 are regulated
F. Spreads are <0.10%. Arb is super efficient

To summarize: The bitcoin market is smaller, but more efficient and regulated, than reported, mitigating concerns around market manipulation.
