Ananonimity is really all you get with "b"koin's (?) plus a lot of market destruction in the microcap investing sector.  Listen closely to the opinion of Bank of America on point, dont confuse blockchain with "b"koin's.  Clearing this mess up is in process now by many countries offshore and a strong movement is rumored that the I.R.S. is in the hunt, so is anonimity wrecked microcap sector and now bird dog I.R.S. hot on your tail and many countries moving to ban "b"koin"s,, really also begins to look like a dark "HOLE".  Blockchain should remain,, bum-coins need to be shut down all-of them 100%,, IMO!
