This statement made me more confused as the person or team behind BTC is unknown but, still people believe in it. If so then should I be worried about the team in case of other coins? So., Confusing
there is a difference between
* bitcoin that has no premine, ICO, fundraising,... and you are not paying the "developers" to get the coins!
and
* and altcoin or token that has premine, ICO, fundraising,... and you are indeed buying the token from the developer who created it out of thin air. that is why people say you should know the people behind the project!
otherwise you should NOT want to know who is behind a project as long as it is
decentralized. otherwise if you are trusting "people" instead of the "project" then you are centralizing that project. same with bitcoin, people trust bitcoin not because of Satoshi or the current bitcoin-core developers. people trust bitcoin because it is decentralized and is doing what it is supposed to without any shady business done by developers like what most altcoins do usually with premines.
