We dont even know what is going to happen tomorrow, and you want us to tell you when bitcoin and digital currencies like bitcoin are going to take over all the system?

It is impossible, maybe not at this moment, but we all are going to see a huge advance about money and how does it works in a few months from now, or maybe in years.

But yes, the whole system is changing right now, and a lot of banks are now addapting themselves to bitcoin and all the other cryptocurrencies, because it is needed.

Lol, a side note: you're the guy who sold Spotify premium that stopped working right after. I didn't know any better because that was the first time I was posting on these forums and understand this whole new marketplace. I hope you were able to refund everyone.

In the next 50 years, BTC may be adopted. It may be dropped. There may be a new alt in it's place. We have no clue what it will look like in the next 50 years, if not the next 10. It's volatility makes it hard to predict where it runs. For now, I believe blockchain could be the future for the next decade or so.

Though the time frame of 50 years is very high, I see that in the future more and more government bodies would be waiting to regulate Blockchain under their control. But on the positive side we should see more and more implementations of the technology in Banking, Finance, Stocks, Industries etc. I bet it should happen within the next 2 years or so. Seeing the genuine interest in this technology by such multi-billion dollar organisations and at the same time seeing multiple startups sprouting the future of blockchain is quite bright.

It's really hard to tell, it will either reach its max adoption and then decline or it could continue to grow and flourish and really change the way the world works as we know it. Of course we all hope for the latter but it is really too difficult to know.

This is an amazing question!

I think the digital economy (I think you are referring to cryptocurrencies?) and Blockchain tech are going to completely revolutionize how we do business, exchange money and more in the coming few decades. I mean do you even remember what is was like living in the late 90's? There were no GPS and everyone used maps - real physical maps to get around. Unbelievable that in just 20 years the whole world flipped upside down.

Now, Blockcahin will be the same. No one will need banks in the future because Blockchain and BTC will allow everyone to be their own bank. I can't wait until this happens!!!

The blockchain will become the supreme way of payment for people that seeks freedom from their government controlled fiat currency. Decentralization will be a big hit in the up coming years thats why some governments tries so hard to ban or regulate it so they can regain control of their customers.

Like some said above, a lot can happen in fifty years. We could conceivably see quantum computers and quantum level encryption deployed within that timeframe. From history we can see that some inventions withstood the test of time. The mousetrap was invented in 1897 by James Henry Atkinson and is still in use today. It is plausible that bitcoin could have longevity due to it having limited supply which could allow it to retain its long term value better than alts with variable supply. Currencies with variable supply are prone towards being overprinted similar to fiat which could be a negative precedent over the long term. Bitcoin also may have better decentralization and development support. Bitcoin has advantages over other alts which could allow it to prosper and maintain its role as king of the crypto mountain over the next 5 decades.

Historically, there hasn't been much incentive for banking or financial sectors to produce innovation or progress. There may be a better likelihood of open source movements, independent developers or hobbyists producing whatever historical innovations we'll see in digital transactions over the next 50 years, than any real progress from the establishment or banks.

Blockchain will be used by different company, and by the government.  I also believe that Blockchain technology will be developed to the point that everything in digital world will rely on it.  Even though 50 years is too long, we can still project that this so called Blockchain technology will be the main thing when it comes to digital world.  Adoption, development and application things that will greatly involved in blockchain for the next 50 years.

I think there are a lot of improvements from the blockchain, not only that, I think in that span of time bitcoin is legalize in a lot of countries and being introduced to the block chain technology and trying to think and discover new possibilities with the use of the blockchain.
