I just started a couple of weeks ago, but it was just last week that I made an investment into it beyond the free stuff. I like the idea that you own your miners and you can sell them if you want down the road. I also like that it has been around for a while and seems to still be doing well. Not many projects can say that in crypto these days. Finally, I know a couple folks who are pretty heavily invested in it and I consider them pretty wise and learned when it comes to this sort of stuff. The fact that they felt it was worth throwing some money at speaks volumes to me.
