It would be very helpful for me to know your experience mining with an FPGA.
I am interested to buy a CVP-13 and I would like to know if it worths it?
Also what should be careful before or after buying it?
fpga lack the type of coins you can mine. Your pretty much gota buy somebodies bitstream to mine some shitcoins that you have to sell and hope it has some liquidity.
Coins like grin/beam will have early gpu access and fpga/asics will lag behind.
In mining, getting in early is more important than getting in later and hashing more. Something to keep in mind.
I think it would be nice to have one fpga at least to play with. I wouldn't build a farm with it until they start having good coin bitstreams to mine with.
