before i traded crypto I ran an institutional trading desk that made markets in global fixed income futures, nowadays my time is 100% crypto however
algo's all the way... i started trading manually back in the day... i was not comp sci or anything i just learned to program from the internet in response to the fact that I couldn't get a fill manually anymore, that was 2008 i think...
Great to see established talent from the financial industry on here.
Yeah, almost all trading is now done through algorithms, so being a system(s) trader is key nowadays.
