Bitcoin was invented to eliminate third parties, which only want a buck for any possible person. Have you ever read the white paper?
I am using Bitcoin the way it was meant and I am advocating for that. I am also trying to help as many people to do the same.
There are some businesses which are necessary to live -- e.g. a grocery store, from where you buy bread, milk and so on. Or the company providing electricity. But you can live -- and live better! -- without many other companies and, for sure, without exchanges (at least centralized ones) or banks. Bitcoin facilitates peer-to-peer transfers so there is really no need to use a centralized exchange to do that for you. Regarding banks, I am coerced, by my employer, to have a debit card where my salary is paid. But when my salary is paid I cash it out entirely in the same day and I pay for the rest of the month only with cash. Nobody is supposed to know what I am doing with my money, besides me.
Yes, I’ve read the white paper. And I do something similar with any fiat money coming to my bank accounts. I don’t cash it out, but I exchange it to bitcoins via Localcoinswap or LNP2PBOT.
But what do you think about miners? Aren’t they that very third party which only wants a sat from any possible transaction? I see professional mining as a move away from the concept of intermediary-free transactions. I would prefer a digital cash system where every user is also a miner.
