Paytm, the payments giant in India has garnered a prelaunch waitlist of 5 million users, according to media reports.  Many companies would die to get to five million consumers in their lifetime.  But it seems Paytm, the giant payments system in a country of 1.5 billion, has no trouble signing up expectant consumers in droves.  While it remains to be seen how many of the waitlisters are buyers versus browsers, it is still an incredible number.
