you only think you own it, can almost guarantee there are engineered exploits and weaknesses known only to few. many peoples bitcoins were stolen/lost/etc who i’m sure thought it was 100% secure. bitcoin was contacted by (and received investment from?) in q tel (aka the CIA) very shortly after creation (by a unknown creator btw). to determine the purpose you need look no further than it’s uses. 95%+ of transactions are either speculation, money laundering or paying for criminal activity.
these are my opinions, reached by (i think) very sound logic, so to dismiss it as an “attempt to defame bitcoin” is ridiculous. i could care less about how other people view bitcoin.
