It is obvious that Bitcoin is not decentralised and a few miners or whatever can completely destroy this innovation.
How on earth can miners destroy the bitcoin system,if you sure feel so, do tell us how they will, miners simply confirm transactions,and there are numerous measures in place to make sure they do not take absolute control of the transaction,other than confirmations and moving it over to the next block
I hell do not see any government in control of the bitcoin,nor ruling body, no insurance company,no headquarters etc...
Thus the bitcoin is definitely decentralized,and only controlled by those in the system
And you're definitely in control of your investments as long as your in control of your private keys
So you honestly think that there are not a handful of whales controlling the price? - if so how is that decentralised? - just another form of control
