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.
Satoshi himself admitted that mining would eventually be done by big mining farms. Heavily decentralized mining was never a major goal of Bitcoin's protocol.
Bitcoin is getting further and further away from the guy in the street, and is now some rich hedgefunds 1% elite plaything.
How it's their plaything? They don't control the price or the network, they are just investors like the others. Bitcoin does not prohibit "the elites" from owning it.
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??
How can it be replaced by any altcoin if those altcoins have even less adoption?
