Well, if the inevitable result of entrusting exchanges is getting ripped off, then yes - I suppose we each should expect the worst. It seems to me no different than any other part of life. If you are going to trust the untrustworthy, you're gonna get screwed. I'm not saying that the thievery is justified. I'm saying that we should regard it as inevitable that enabling scammers is going to result in scams occurring.
I guess this one is on me for not clarifying. How 'bout I say f2f - as in face-to-face. I've had a 100% track record so far with this. As have all of which I am aware.
I must have misunderstood you then. Perhaps due to an earlier quote from your OP:
I have no idea what you are indicating by "What good is fiat without banks?".
I don't think there is any particular 'supposed to do'. Crypto is a technology, not a director of human activity. Maybe start by asking what it is that you want it to do for you? Hoarding is a possibility, sure. If more of the planet comes onboard, you're likely to accumulate purchasing power by simply holding a fixed amount of it. Of course, with no activity, the world may not hop onboard. You can use it to purchase things.... the list of vendors is large and growing larger by the day. I personally feel that remittances (a multi-billion USD market with astronomical profit margins) will be the first real 'killer app', but I expect that it is dependent upon several more years' worth of infrastructure buildout.
Despite the cynicism I display in the opening sentences of this post, I am hopeful that crypto continues to grow, to the point where it overtakes fiat in gross global economic activity. I see this as more likely than not (your analysis may differ). A wonderous world awaits humanity if we can wrest monetary control from the hands of self-rewarding parasitic warmonger vampire-squids. (That last sentence should be a clue that I suspect that you and I likely could have an extended discussion on the merits or demerits of the fiat monetary system - but that should likely wait for another thread).
