I'll reiterate what Zumzero already posted earlier since it is very relevant to this conversation:

Day One of the conference was capped off by angel investor and bitcoin advocate Roger Ver and he did not disappoint. When asked about the future value of bitcoin, Ver was understandably bullish about price.

“It’s very, very clear that it is going to be higher than it is today,” he said.

Perhaps the most intriguing though that Ver conveyed was his opinion on mining. “It’s a market that has huge potential,” he said. Ver pegged bitcoin mining as a $1 billion industry given the roughly one million coins that will be rewarded over the next year.

“I don’t think anyone understands how big this industry will be,” he said.
