Dilution is ending, here is why, buyback is highly speculated to be underway via negotiated transactions. The CEO explained on both recent CC that he is not at liberty to discuss the details of the buyback until OTC shows current. There is nothing stopping him from using brokers to gather the shares.
The brokers to date have managed to move/collect a total of 19bill shares. Buyback was to be for 15bill shares or more as needed. I feel very strongly the brokers were sucking up all the shares hitting open market these last few months. Below you can verify the data on Finra for what brokers have done and see that more are involved than before.
