We have all heard the story of the pizza guy getting paid in BTC, yet some 10 years after Bitcoin was made, hardly any shops accept BTC in the great scheme of things.
It started off as a project that would enable the regular guy with a modest pc to mine BTC, now you need a huge farm to be able to mine effectively.
Bitcoin is getting further and further away from the guy in the street, and is now some rich hedgefunds 1% elite plaything.
What is the future of Bitcoin in your view, will it render itself useless and be taken over/killed by a better suited cryptoproject, or are we stuck with it??
Totally bitcoin has not failed to its purpose because bitcoin is still under a process of adaption and it is still growing in the past and coming years.
Maybe bitcoin is not really great when it comes to spending at this point since the market price is so volatile so it would really make sense just investing bitcoin instead of using it in buying things in a store.
But still, I wouldn't say it's a failure since the process is not yet over and in the coming years, it might succeed as a digital currency that you could spend.
