From your experience and the present landscape of the mining horizon, what will be your genuine advice for someone interested in mining bitcoin, to abandon the interest or to continue?
Also, if you think that they could still benefit well, what tips can you give from the lessons you have learned?
By tips I mean information like, best mining equipment name and model to use, and then other hacks you discovered on your own.
If your electricity is more expensive than 6 cents, then you don't need to try.
If you really want to, then buy an old ASIC for 90-100 terahash s19 for 400-500 dollars and experiment with mining. If you like it, then buy more modern equipment.
If you don't like it, then sell this ASIC for the same price or a little cheaper.
