I always wonder what might be the reason of centralised authorities not accepting the power of Decentralization and then found the reason,if so decentralization becomes the only means for the transactions then most of the regulators and authorities might be jobless and so they are putting maximum to let down this technology by creating a hype that all the crypto currencies are scam and you can making nothing out of them investing,so we Crypto enthusiasts need to put our maximum efforts to empower decentralization .
Bitcoin is already taxed and almost everyone in USA pays taxes for the profits they made from the bitcoin trades (I mean some people don't but there has always been tax evaders). Hence decentralized means nothing when it comes to regulators. Regulations for usage is not based on decentralized ideas, regulations are about how they can regulate the way you use it and how you should pay taxes and how you can't do illegal stuff with it and so forth. Decentralized means they can't touch bitcoin, they can't touch bitcoin itself not the bitcoin you own, they can take your bitcoin just fine but can't make bitcoin 210 million instead of 21 million, can't make the blockchain 1 gb per block, can't make transactions come to a halt. Basically decentralized is not a way to run from regulations but a thing to keep it untouched by any one person with power.
