Not really. Conversion to cash is limited to Rs.4000. Rest goes into your account. If you convert more than 2 Lakhs, that is notified to the IT authorities. You can't withdraw more than Rs.20000 per week or some such limit. Trickling down will take a long time, and even then most of it will be watched. If someone is withdrawing more cash than they ever did before, the govt., will probably question them beyond certain limits.
