The Osprey Electronics E300 14 GH/s kHeavyHash may have been the first FPGA miner for KASPA on the market, but apparently it won’t be the only one: new FPGA and ASIC miners for KAS will appear in the near future.
The E300 was originally priced at $4,999 and is currently available for $5,199 with late May shipping and 400-500W power consumption, but it looks like the device is now facing competition from the MultMiner M2 FPGA miner ( this appears to be a rebranded Blackminer FPGA by HashAltCoin with kHeavyHash support) offering 8 GH/s at 1kW or 10.5 GH/s at 1.3kW hashrate, as well as support for DigyByte, Tellor, Qitmeer and Kadena at a price of over 2000 USD.
The other new variant seems to be called the SuperScalar K10 kHeavyHash ASIC miner, which promises 30GG/s hashrate at 1700W power consumption and a price around $8500-10000.
All of these FPGA and ASIC miners for KASPA (KAS) are quite expensive and while they outperform the GPUs that most of us are currently using to mine KAS, they still may not be a good investment and the reason for this is quite simple – KASPA (KAS) is the only coin that currently uses the kHeavyHash algorithm, and the block reward is steadily decreasing every month (see the emission curve for more details) and hashrate and difficulty are constantly increasing.
Thus, buying a very expensive ASIC miner for mining kHeavyHash that cannot mine anything else is very risky and can lead to loss of money, it is much wiser to invest the money you pay for the equipment in buying KAS, which can turn out to be much more profitable investment. The situation with FPGAs is slightly better as they can theoretically be reprogrammed to mine other algorithms and coins, but there is no guarantee that this will happen, so it’s still quite risky, and again, it’s probably better to invest directly in KAS than buying FPGAs or ASIC miner for mining with it.
If you have an old Blackminer F1, F1mini, F1+, F1mini+, F1-Ultra or F2 purchased from HashAltCoin, then you should pay attention to them, as they received a firmware update to support KASPA (KAS), although the bitstream for support for the kHeavyHash algorithm is called, oddly enough, “Kasper Bit”. Go to the HashAltCoin support section to download new firmware updates for these devices that will provide KAS support, and depending on the hardware you have, you may be lucky enough to get “free” MultMiner M2 features.
Surely this would be a good enough reason to revive these miners from obscurity, even if it is just a small mini miner that is not that powerful, it will still be able to mine a few Kaspa coins for you profitably due to the high energy efficiency of these FPGAs.
However, keep in mind that in order to access the official HashAltcoin website and download firmware updates for Blackminer, you may need to use a proxy or VPN.
