The second-largest cryptocurrency platform, Coinbase Global (COIN) reported solid third-quarter earnings on Nov 2 after the closing bell.

These include First Trust SkyBridge Crypto Industry & Digital Economy ETF, Fidelity Crypto Industry and Digital Payments ETF, Global X Blockchain ETF, iShares Blockchain and Tech ETF, and ARK Fintech Innovation ETF.Adjusted loss per share came in at 1 cent, much better than the Zacks Consensus Estimate of a loss of 54 cents.

Revenues climbed 15% year over year to $674 million and edged past the estimated $657 million.Trading volume dropped to $76 billion from $92 billion in the previous quarter and $459 billion in the year-ago quarter.
