Why shouldn't GPU, FPGA, or ASIC miners participate in Kaspa testnet?

GPU, FPGA, and ASIC miners are asked to stay off the Kaspa testnet to prevent any single miner from capturing too large a share of the network's mining power. Testnet exists so developers and users can experiment safely — if powerful mining hardware dominates it, the hash rate becomes centralized and the testnet no longer reflects healthy, decentralized conditions. Keeping powerful miners off testnet ensures experiments and tests produce realistic results that reflect how the main network actually behaves.
