The flexibility of bitcoin needs a backward reaction, A transaction that can easily be reversed if any mistake comes up,Bitcoin is growing and moving so fast that about 70 percent of world will ready to have bitcoin as a coin in there wallet.
And that's what separate this technology from the banking system. It is called BYOB (Be Your Own Bank), so naturally he can totally control of everything, so in a sense it is your responsibility to be careful where you send your bitcoin. We don't need this so called backward reaction or whatever. And that's why it is decentralized as well, no third party needed, no name, just bitcoin addresses.
