The Lemon Fool

I have ended my crypto fund venture, I am out, for completeness, since I mentioned some return figures here earlier, after fees the GBP return was 1306.45% over exactly 4 years. I hope I haven't made a mistake but using the actual dates and cash flows XIRR shows 94.06% (seems low).

That sounds about right. Doubling each year means it goes:

100
200
400
800
1600 after 4 years, so your 1300% is in the right region.
