So what do we have 6 months after the majority of customers have received their bcu1525 fpga boards? Mining income is about 2 usd per day bunch of folks are trying to sell this equipment on secondhand market even at $2000 ($3250-3600 initial sale price).
Acorns are now pure doorstoppers, there are no such thing as GPU assist.
And guess what? Surprise! SQRL launching a new board, advertising it as a beast hardware for x16r.
It seems that BCU1525 owners have to forget about any new bitstream releases for their equipment, especially for x16r algorithm. SQRL just want you guys to buy their new fancy boards.

I want to repeat: mainly only miming hardware manufacturers and hardware resellers earn money in crypto mining  sphere.
Currently crytpomining is a zero-sum game, where miners will always lose, doesn't matter what kind of specialized hardware you are using : ASICs, FPGA.
bcu1525, Acorn owners are screwed, there are no chance that they'll be able to payback investments even within 2-3 years period
