Why is this referred to as a "hoarding" problem? Why is saving not the correct term for this? To me, it's derogatory to call saving hording. At some point, the coins will be spent or sold. Hoarding is what those people on TV do, keep it until it is trash. Unless it's your plan to keep your BTC until you format them away, it's not hoarding.
Correct.
Because bitcoin is a
deflationary currency it will be attacked by all who believe such currencies are doomed.
Attackers (debaters if you prefer) should use logic to discuss the relative merits of fiat currency versus bitcoin. However, they are likely to also try emotional attacks, and calling bitcoin users "hoarders" is an emotional attack. It isn't logical, but that wasn't the point of the attack.
