All of human history (and perhaps biology) has always been about continually trying to accumulate more even at expense of others. Bitcoin doesn't detract or contribute to this human nature.
If you really want to talk about profiting off the backs of others, look no further than interest bearing loans. It isn't for no reason that parasitic and immoral practice had been declared prohibited in Islam, Judaism, and Christianity. Most, if not all of the economy today is based off of interest, and the sooner we get rid of it the better.
Well what I find ironic is you are against the concept of interest but consider a cool technology like blockchain an "investment". If you were really so righteous about economics you would realize turning cryptos into "investing" is a total scam.
