Firo cryptocurrency, formerly known as Zcoin, held another hardfork on October 26, in which it changed its mining algorithm from MTP to FiroPow. Whereas MTP hash rate only depended on the GPU chip, FiroPow mining directly involves the onboard memory of video cards. FiroPow is another version of the ProgPow algorithm, to which the transition of Ethereum cryptocurrency was once considered. FiroPow, like Ethereum, has a Dag file that must be kept in video card memory, but the hash rate of the video card depends more on the performance of the GPU chip than on the memory bandwidth. Firo cryptocurrency's DAG file size was originally set to just over 4Gb, so all video cards with less video memory will not be able to mine this cryptocurrency.
The following miners support Firo mining on the FiroPow algorithm:
- Official reference miner (0% Commission, not suitable for new AMD models)
- Nvidia GPU: T-Rex Miner (Commission1%)
- AMD GPU: Team Red Miner (Commission2%)
- AMD GPU: SRBMiner-Multi (Commission0,85%

Conclusion: Firo developers switched its cryptocurrency to the more Asiki-protected FiroPow mining algorithm, which is usually done to increase decentralization of the network, making it more attractive for miners and investors. But the decision to install DAG file more than 4Gb reduces decentralization, because after hardfork numerous miners with RX470/480 and RX570/580 cards with 4Gb video memory will not be able to mine Firo cryptocurrency. Apparently, not only we, but also investors didn't understand that decision, because Firo's value has not practically changed since the change of mining algorithm was implemented.
