i don't agree on bitcoin mining being a bad way to earn bitcoin, it depend
if you have free electricity or at least very cheap, you can do it without thinking, you will have a very high chance to roi, without doing the trick of selling your miners after 3 months
with that trick you can actually take big profit and in a short time, if you invest big
Im never hear about free electricity, all country give high fee for miner, i think buy and hold bitcoin is better than mining at this time
there is a simple difference, with mining you can increase your total sum of coins, when roi is achieved, with simply buying you can not, unless you do trading
but you say simply buying and holding so...
