Earlier quoted context omitted.
I find it very funny that BTC advocates bring this up all the time, yet inflation of USD is considered to be an enormous threat. Surely both of these things cannot be true.
I am not advocate for Bitcoin, but I assume prices in BTC would raise with inflation like any other currency
This encourages people to hold BTC because its relative value increases over time. Thus BTC by being deflationary encourages holding and not spending. It will lead to a less dynamic economy than if we had an inflationary currency which encouraged spending/investment.
