For home miners, the question is rarely "will I get rich" - it is "is the electricity bill smaller than the MLRT I earn, and do I value participating in the network?" This guide walks through the four numbers you need: your hardware hashrate, your power draw, your electricity rate, and the current MLRT block reward / market price.
The honest answer for most home miners is that mining a CPU/GPU coin is closer to break-even than it is to profit. The value is in supporting the network, learning how mining works, and accumulating small amounts of MLRT over time. Treat anything else as upside.
