Is Bitcoin the final form for humanity?
Decentralization has long been dreamed by all different social models, is there another step to be taken?
Can humanity (humans) learn to hang on and manage their finances?
Or is Bitcoin an experiment to show that we're not capable of managing our own belongings and do require central authority?
No, Bitcoin isn't the final form of decentralization for humans because know one knows that what the future holds for humans. The things will be very different from today in coming decades and the technology may reach very high heights in future. Although, Bitcoin is the best form of decentralization till date but considering it the final form won't be justice because who knows that in coming era there will be more and more inventions that could take decentralization to another level.
The Bitcoin is truly a savior for the lover of decentralization and its the king of the crypt-currencies, and only after its creation the decentralized projects started appearing. In the world of decentralized finances there isn't a competitor of Bitcoin and there won't be one in coming years, but the decentralized technology is not limited to finances only and there have been other decentralized technologies like decentralized VPN's and Tor. Those things are at another level of providing decentralization and may help you to browse internet anonymously without sharing your personal IP address.
