Part of the revenue seems to be related from HEX, which is currently yielding 40% APY. While I am not sure HEX will continue yielding these results, it's very clear that its less likely for this APY to grow much higher. Hence your calculations are off, the growth would be purely based on compounding and not sales.
As it has been alluded the software service side of the business is not moving high amounts and I believe they recently had a transaction to sell part of a software suite.
Previously it was mentioned the "asset drawdown" was "phony" but it's clear that they are selling part of their assets (cryptos) for profit. Any discussion steering investors away from what's happening is based in ignorance.
