Again, PBmining could dispel all rumors/doubt by simply providing a mining address. Why don't they?
Because they're clearly satisfied with how their service is turning out and doesn't feel the need to please everyone that's screaming ponzi? 
That makes no sense. Why would you purposely turn away potential customers?
If there are so many people screaming ponzi, wouldn't the logical response be to prove you are not a ponzi?
Why would PBmining spend so much time/effort implementing a complicated coin mixer AFTER people begin the ponzi accusations?
Did Mr PBmining wake up one day and think to himself "how can I make my company look much more sketchy and make it much harder for me to acquire customers?"
PBmining could be massive if they would have just proved their legitimacy 10 months ago. I'd guess they could have more 10PH/s by now if they didn't limit their customer base to gamblers and gullible noobs.
Fact is that people do get paid, and they genuinely like it.
^ Said anyone who ever participated in a ponzi before it collapsed.It's just sad to see the bitcoin community falling for the same scams over and over which can be easily prevented. If the everyone would just adopt the most basic standards like requiring proof of mining via a mining address then 99% of cloudmining scams could be avoided. Although I think most people already require simple proof of legitimacy, there's a never ending wave of noobs who oppose the idea.
But you're right I think I've made my point, I'll leave and let you guys enjoy your gambling. I just hope you guys are honest when spamming your referral links and don't pretend pbmining is a completely legit mining operation without massive risks for a tiny reward.
What's your purpose? Letting people know that you think it's a ponzi? You have done that multiple times already.
It's up to PBmining to decide how they run their business, if this is how they want it, then let it be so.
You clearly are no fan of PBmining, why not just skip them and focus on other things...
Maybe he/she have mental condition.
