No random person controls a crypto-currency lol. Wait wait, I thought you knew how cryptos work? I mean no disrespect to you, but do you know the maths behind crypto-currency? If you have studied discrete maths, probability, statistics, and information theory, cryptography and number theory, you would know that it's literally mathematically/computationally IMPOSSIBLE for someone to *control* a cryptocurrency like bitcoin.
And the protocol design itself is open-source, controlled by a public community of experienced scientists and developers, and anybody can contribute in it, if they have enough achievements and experience. I have published a few research papers myself, on security of bitcoin blockchain.
