Standard Bank tests current account-linked bitcoin wallet

This is very bold of Standard Bank. They'd have to offer it as an investment product with full disclosure on risk. And how do they ensure that the wallet does not EVER receive funds from the bitcoin exchange? There's no guarantee of counterparty ID At all..... 

At this point in time, it is probably MORE likely than not, that there are laundering (tax evasion) or criminal proceeds of crime (drug sales) attached to bitcoins than cash. They say crime uses 30% of the cash in an economy, but it stays black the rest of the market is realitively clean. If you buy bitcoin with Rand, who knows who you've just aided and abetted in placement. This is a direct conduit into Standard Bank. Eeek. 

Any system has bad actors and good actors.  When the good actors out number the bad, it becomes more difficult to discredit the system.  Is the internet discredited by pornographers and paediphiles ?  Is the credit card system discredited by frequent fraud and theft of credit card information (the fact that such data needs to be provided in order to effect a transaction being it's supreme flaw) ?  Is the entire banking system discredited by a certain global bank recently fined $2billion for money laundering for South American drig cartels and thereby being indirectly linked to the untimely death of 80,000 people ?
