Monero is one of the only cryptocurrency's supporting CPU cryptocurrency mining, making Meltdown patches a concern.Most cryptocurrencies today are mined with specialized hardware targeted at crypto mining, or a Graphics Processing Unit (GPU), which means the CPU based 'Meltdown' vulnerability has no impact on performance. However, that's not the case for all Cryptocurrencies. Monero is in the top 20 currencies, and it supports mining via CPU. The reason that is concerning to Monero miners is because the CPU is affected by the Meltdown vulnerability. Patches to fix 'Meltdown' reportedly can have an impact on the performance of CPU's, unfortunately.Intel made a statement about the performance impact of Meltdown security patches: "Any performance impacts are workload-dependent, and, for the average computer user, should not be significant and will be mitigated over time"That can be a big concern for anybody using their CPU's to mine cryptocurrency, or any other CPU heavy task...
