Yeah, I'm not making major purchases now or anything. And I definitely wouldn't mine it if doing so becomes unprofitable (though in fact it seems very profitable right now due to hype). Price-wise, IMO it'll start looking like a good buy if it hasn't been superseded by clones in about a year. I'll be looking for a point of low sentiment at that time. Some people have said that you'll need to wait like 3 years before it escapes from its inflation pit, but keep in mind that Bitcoin's inflation-rate-over-time was roughly the same in its first 4 years; such high initial inflation is why you saw people buying pizzas for 10k BTC like it was nothing. But growth, if it occurs, can overcome even pretty massive inflation.

The tech is just so awesome: a high degree of privacy combined with by far the best decentralization-preserving on-chain scaling tech ever devised, plus several smaller innovations in grin's particular implementation. Even if it was somehow guaranteed to halve in price every year, I'd still consider it cool and want to do something with it.
