They "use" Internet and Information Technology.
Very fast global transmission. These are extremely valuable attributes for a company today. That is the real secret.
That is why Steemit and the Wallet we have will do the same with money as these companies did with their branches.
Exactly as nobody did understand that these companies would be the biggest in the beginning. Nobody or very few understand that Steemit with their Wallet will be the biggest. Think about it, nobody can transfer money as fast and with no cost as you can from your wallet to another Steemit Wallet anywhere in the world.
Think about this:
You go on Steemit and write something (a post, a comment, a reply), vote and get paid to your wallet.
When did you get some extra money in your bank account for asking your bank about something or tell them your opinion?
And they can not even transfer money for you fast enough?
And this cost you money?
So, who will be big?
That is the real secret!
