Just think if the price gets increase even more and more old miners will be interested to mine crypto again and that must be an unpredictable factor to make another adjustment to the difficulty in the network. that's why i was thinking for a twice before i did it. i have a plan to bought mining rig but after seeing how the difficulty adjustment work and i run MN and it's more profitable than mining. I can earn about $50 in a week. It consumes less than $1500 to be MN

But mining seems not too bad right now.
