Snapped a pic.
Gotta remember this moment.

Almost exactly 3yrs ago I was here in Houston, TX at NAPE talking to O&amp;G producers about mining .
Not one of them took me seriously. Most laughed.

Today I’m in Houston with 100+ O&amp;G people — talking bitcoin.

What a time 💯 https://t.co/YU85RNdvYB
