Negative creep

This is an incredibly troubling aspect of the push toward a cashless economy. Not only does it marginalize the unbanked (those who can't bank due to illegal immigrant status, or other mitigating circumstances), but it's also an incredibly powerful tool for population control.
It removes the agency a modest savings give us, by concentrating all wealth under the control of a select few anointed conglomerates. It also allows onerous policies like negative interest to be a new, truly inescapable regressive tax regime.
Edit: notahacker makes a compelling point that negative interest is likely less regressive than inflation. I thought it was something worth bringing to the root of the thread.
Also majority of hash power doesn't decide everything. If miners decide to create cartel where they change the protocol rules (via hard fork), they still need a place where they need to sell those mined coins. So exchanges/services/merchants should be in the same boat.
Also there will be always a lot of competing cryptocurrencies, where users can switch to when needed.
What really happens is that power is shifted away from regular people (who can at least assert some influence on those making the changes) to those holding capital.
There is a reason why negative interest rates exist now. It would be foolish to assume that those reasons go away and won't be implemented into cryptocurrencies in the future if they are used widely.
If miners are so powerful that they can change the protocol rules, why they wouldn't just raise the block reward? ( increase inflation/monetary expansion)
I just don't think our current problems with currency go away just because we use cryptocurrency. There is no reason to. Central banks don't enact policies because it's fun but because they think it will have a certain effect. People will find a way to do so in the future. Whether it's called "Inflation" or "negative interes rates" or whatever is not relevant. The only thing that matters is what happens to people's money.
Oh, and it would be much easier if you would actually reply to my comments (instead of yours). If neccassary wait a few minutes to do so.
Until large numbers of retailers accept bitcoin directly it's just a different currency with a less stable exchange rate, lower liquidity and a higher potential for low tech users to get their money nicked.
It's also not regressive, negative interest is simply flat.
You need at least some liquid capital, and those with the least money will always be 100% liquid (or very close to it), and are hence the worst off under negative interest.
If nobody will refinance (often more true for poor people), this puts them in a double bind.
The cost of negative interest is likely less regressive than than the existing system of inflation.
It will be interesting to see how this untested financial environment will settle to equilibrium, and what our world will look like as a consequence (like you mention, more VAT? Or fewer taxes as borrowing grows cheaper?).
Discouraging illegal activities (any illegal activity, not immigration in particular) is a _feature_ of banning cash, not a bug.
Getting funding to start a business in Japan is rather hard. The good old fashioned way was to get a loan from the bank. Japanese banks simply prefer to avoid risk at all costs, deposit a pile of cash with BOJ and collect almost 0 interest :) Better than those risky loans.
* and of course it doesn't hurt to weaken the currency while at it. Everyone and their dog are doing this and it is getting really hard to be the one weakening the currency the hardest.
I see this speculation from time to time, but no data to back it up. I wonder, who benefits from such rumors? To my limited understanding in economics, negative interest rate is to encourage lending vs hoarding, so while money is moving, you don't actually "lose" them?
Would you miss it?
I think this fantasy some people have of banning paper currencies pretty well points just out that the people who propose the banning, have no idea how the world works.
As long as you can barter things of value, like a brand new Macbook for bitcoins, bitcoin will survive.
Sites like LocalBitcoins would very quickly cease to exist if there is a concerted government effort to ban Bitcoins.
In the same sense as linux never became popular desktop OS, but it has gained new market share from elsewhere.
