Totally agreed as it will certainly grow enormously but the aspect that needs more input is the security of accounts.
If I could code, I would develop and app that could track the status of all accounts.
Should an account be hacked, this app will re-instate the status of the account and track the hacker whose account will be frozen and forfeited.
Maybe just a pipe dream and sorry that it's a bit off topic.
