Got it. Thanks. But what about a realization of additional functionality that, say, will let users,
first, analyse its transactions history,
second, manage its profits,
third, automatically decline suspicious income transactions,
fourth, holding some sum of money on sender's account (if it is contract arranged),
etc.
Why are you comparing bitcoin functionality with that of your investment adviser/ personal banker??!
First and foremost, bitcoin is a method to exchange value without the need of a middleman with the assurance that the transaction is irrefutable.
This has only been possible until now with an intermediary in between to back the value. Bitcoin needs no backing as its backed by the continuously growing ledger on its blockchain.
If you are talking about additional functionalities then all of it is possible with bitcoin sidechains.
