Tribus, Keccak, 0xbtc algos are dead if speaking in terms of profit
The last coin which is used Phi1612 algo is a small shitcoim called Folm with about $100/day trading volume on exchange, and even this small coin is going to fork with algo change
On Phi2 even old RX Polaris are provide almost two times cheaper hash cost. $44/Mh vs ~$25/Mh. nvidia Pascal - even bigger difference
Zcoin - the biggest Lyra2z coin is going to fork at Dec 10th, hashing algorithm is also will be changed. Also 35Mh it's very overestimated hash rate for this type fpga chip... real achievable ceiling is about 25mh/s
On cryptonight v8 fpgas can't achieve any reasonable hashrate due to sqrt and div which was added into V8 cryptonight codebase. in terms of hash cost fpgas can't beat AMD Polaris and nvidia Pascal GPUs.
No doubt that payback period of these fpgas will be much higher than 1.5 year. (very optimistically) and we are not taking in count huge amount of bcu1525 and chinese copycats which are hitting network these days
Owners of all this great mining equipment will be screwed with unreasonable roi period.
I want to repeat: nowadays mainly only miming hardware manufacturers and hardware resellers earn money in crypto mining sphere.
This is a game where miners will always lose
In near time we'll see more and more coins forks with asic, fpga resistant algos.
Thanks for you inputs, but my friend i think you are overly pessimistic
HW resource and capability of this fpga device is very powerful and can easily adapt to the future algorithm changes. besides there are always new coins popping up, programmer can develop new algo support on fpga board with decent hash power. and have i mentioned about power difference between gpu and fpga?
Again, i believe it would be really hard to become fpga resistant.
Hes not being pessimistic, just being honest. No doubt FPGAs are highly capable, but not profitable with the algos you have presented.
we have not finalized the algos list yet, and at the end of day fpga of this price and performance should outperforms gpu in terms of ROI, and takes much less power. there are already many secretly mining using custom design fpga boards, we want to start an open fpga project that everyone can have access to.
