I hope there's still some spots available by the time bitcoin falls to $3.66, because I'd sign up at that price point. Its worth two subcriptions at $1.10. I don't think it will, but if it goes below $4, I'll pay.
1 BTC is 1 BTC. And I humbly predict: it will still be 1 BTC in the future.
In other words: I don't quite understand your thinking, unless maybe, you have no Bitcoins at all. Because if you do, that service will be no less expensive for you in the future than it is now. 5 BTC is 5 BTC.
so when 1 zimbabwe dollar went from a 1$ USD value to whatever it became later, its still 1 Zimbabwe dollar so whatever was price 5 Zimbabwe dollars (ie: milk) is worth 5 zimbabwe dollars when its value is 10 000x less in USD? I think not
1 BTC is 1BTC, but 1 BTC now does not mean you can buy the same stuff with it tomorrow or in a year
