Very cheap electricity, good idea to buy an ASIC to mine BTC?

Hello everyone, as the title says I live in a country where the electricity is very cheap ($0.03/Kwh), would it be a good idea to start mining BTC with an S19 with the upcoming halving? At the current price and difficulty it would be around 0.0004BTC mined per day, it’s still quite profitable and pretty much double the average salary here, but the miner would cost ~20% higher to bring it here.

So my question is, how stupid is this? I’m not planning on selling any BTC other than to pay for the electricity and hold long term until 2025.
