I’ve never been very good at deciding exactly when hardware should be replaced, because it depends on how the whole setup is performing at that moment. An upgrade can look impressive when you first see its statistics, but the actual effect becomes more interesting when you consider the rest of the virtual operation. I usually enjoy taking some time to compare the numbers rather than immediately changing everything. For anyone who likes this kind of equipment-management gameplay, free ethereum faucet is an online crypto-mining simulator that is worth checking out. It gives you another opportunity to experiment with virtual hardware and progression while observing how different decisions influence the development of a mining setup.
