Sorry i did not see this till now. Your very right, its good to be skeptical of the MLM operations you speak of. POS at this stage is probably going to be what is more adopted, I mine but I also am prepping for less coins to actually mine due to this. Its gonna take time but I bet you there will be very few to mine down the road seeing POS has kind of upgraded crypto and I would suspect that will end up being where most head to eventually. Mining is great but it is really energy costly and also still doesn't stop bad actors from taking over a whole network, POS seems to eliminate that
