I bought a bobcat miner like 3 months ago and i have to say this is the worse investment i made in my life. Helium as a coin is good but all associated to mining is weard. Nothing works as should. Terrible system and not support at all. Sometime you have to wait for 2 days in order to receive 6 or 10 cents. I know more than 10 people and same problem. At this point I will get back my investment in 10 years. Like always you buy with lot of promo and very soon you find that not even close to the median in the market. I can see lot of people in the Helium chain that only critics to other ways of mining how if the worse system of coin mining is Helium. Hopefully this thing find a way to make it work because like this maybe in a year will collapse. The only good thing is the project intention but people behind can not compete at no point in this industry. I would recommend instead of investing in a helium miner but and sell the coin it self that you will make more profit because mining helium you won't go nowhere.
