When something highly disruptive as blockchain applied to economy starts to grow exponentially and attracts the most brilliant brains from around the world, the second step is attracting big money to build up new things.
That's what they also said with the advent and the boom of the internet. Fortunately though, they were not wrong, and the big money actually made something happen on the entire web. Developments on infrastructure, alongside bringing the tech closer to people really helped a lot on our present state.
Which are the newest and most important trends and stuff that will came alive when institutons and big money will enter in the cryptospace?
That is IMO not something we know right now. The only goal of financial institutions and the big guys is to develop the blockchain tech and integrate it into their systems. Not much for actual development but it
still helps if you'd ask me.
Will be only a speculative journey or do we will be able to change the way we live on this planet for better?
In the meantime, the hype for bitcoin as a speculative asset isn't waning, so in the short-term we'll see it mainly as an investment vehicle and not an actual tool for liberating the woes of the financially oppressed people. Perhaps it will never alleviate the weight of poverty to these people, but it can still help redistribute wealth in some other ways.
