it would be interesting to price out what would be the bare minimum one would have to spend to set up a small HFT server in a colo for a year... another post perhaps... five figures for comp (w fpga networking modifications), few grand a month for data center... market data... it will def eat a six figure hole in your ass and thats before you've done any trading. and of course thats for just one computer in one market lmao. if you need a microwave line now we're getting costly.
a trillion might be a bit overkill LOL. however, for single market HFT, its definitely something that newly minted crypto millionaires could start to think about however, not that i'm advocating anybody to do anything with that statement, just to illustrate scale (disclaimer)
