Litecoin is equally cheap, has fast block times and no such risk.
Neither will scale sufficiently without off-chain transactions.
There's no need for rhetoric comparing BTC to gold. It's not gold, it isn't like gold, and we dont need another form of gold. Let Bitcoin be its own thing.
As long as cryptocoins aren't accepted as much as fiat currency (and they're not even _remotely_ near 1:1), they'll be in lower demand during less glorious times. Practically nobody (less than now) will accept cryptocoins then because you can't use them to buy anything worthwhile. A man's gotta eat, and keep the chin above the tide.
Maybe we can do much better international trade with it tho.
