Hello All,
  I was working on some crypto platform. Say the platform has 1000 users with unique & single wallet address for each user.
  Any time they can deposit to their address & start using the platform. I will do a cron API Call to blockcypher API &  pass each address to get their balance, & update to DB.  But it is fragile, as the user grows up, it difficult & slow to update balance & the cron eventually DIES.
  Is there any better way 2 update balance & transaction to the platform DB.
