Bitcoin will surely hit $1 million/coin due to inflation. What's important is 1 bitcoin = 1 bitcoin, though I'm pretty sure it wouldn't be the mindset until we haven't see merchants and people alike using bitcoins for everyday use.
True! Merchants need to ease out with its type of payment processing And when trust and credibility conquers their faith o meter nothing can stop Bitcoin's price rise! Also hoarding is an important factor since the coins are limited and by hoarding you are potentially creating a demand in the market, which may eventually lead to the price hike again
