BitCoin is NOT a currency. Any business is rolling the dice accepting BitCoin with how volatile the price is. With how rapid the price swings (mostly down), no logical business would/should accept BitCoin. No different than gambling. To my knowledge my dollar last week is still a dollar today, not true with BitCoin, you would have taken a hefty loss this week only!
To my knowledge, my bitcoin last week is still a bitcoin today, so GTFO.
One dollar has still the same approximate value. With 1.30 usd you could buy 1 euro.
But between now and 3 months earlier, the value of bitcoins changed a lot
