Just was pondering this, I started a bitcoin mining company 5 years ago and we initially were going to source with FPGAs but ended up using ASICs instead due to the increase in speed, ASICS are dumber and faster than FPGAs. Why is every HFT using FPGA, are they just copying each other rather than doing research on their own to see ASICS are faster for the same jobs?

- mining algo is quasi fixed. The only challenge is to design and implement it in the most optimal way, which is a slow process. It is driven by simple switch from 12 nm to 10 then to 7 nm TECHNOLOGY. So, it fits into business cycle of months: make design of ASIC, adopt circuit design to new technology, speak to producer fabric, check test ASIC (or maybe buy the board printing machine (10 or 7 nm) yourself and do printing in-house), etc. etc.

- trading algo is not fixed. if algo has stopped to perform, that's it. You have to design and backtest new ALGO. Associated business cycle is much shorter. We are talking about weeks, may be days.

FPGA is reprogrammable while attached to the computer. ASIC is not. If it does not perform, you throw it into the bin.

Ahh, yeah this is true that ASICS can’t be re-programmer while FPGAs can and as you probably can tell, I’m new to this :P. I thought some of these funds have go to algorithms that are more fixed in nature versus others that are changing, and that hft algos would be more along the lines of being fixed.
