      How are @TMobile @ATT @verizon not being raked over the coals for this? 100s of SIMs hacked due to their negligence.http://fortune.com/2017/08/22/bitcoin-coinbase-hack/ …

      Hyperbolically, the general public consists of people who've never heard of Bitcoin, & ppl who are unknowing victims of ICO pyramid schemes

      It has nothing to do with cryptocurrency. Attackers convinced customer service reps to transfer control of cell #s to reset passwords.

          This will eventually lead to pressure being brought to bear, but 100s of accounts aren't going to cut it.
