Bitcoin won't break $500 a coin, likely will sit around the ~$250 range with occasional jumps over $300 and below $200.
People need to start comparing Bitcoin to other payment methods, and they will clearly see why Bitcoin will never have enough demand to "go to the moon," most of Bitcoin's current users are speculators that have no clue what they are talking about.
Bitcoin's biggest issue is that is not consumer friendly: Buying Bitcoin is time consuming (and costly when you figure in fees associated with acquiring Bitcoin + risk of volatility), very slow (to reach 6 confirmations takes several hours... lately its been taking ~1 hour to get even a single confirmation), no ability to chargeback (this is NOT a plus), and other hassles (security issues, learning curve etc). The only thing Bitcoin is better than using the dollar for is to purchase illegal goods.
I see bitcoin being a bit like electric bicycles (ebikes).
There are already lots of forms of transportation and most work fine for those that prefer each type for their particular needs. I see cars as being visa etc. Ebikes will fill a niche but that niche can be quite large worldwide.
Remember bitcoin is not and never set out to offer chargebacks. agree that is a drawback if competing for the car market but not for the ebike market which bitcoin is.
Bitcoin is ideal for non chargeback situations eg sending money to friends, relatives.
Agree it is cumbersome but some of that will improve when regulated exchanges etc are set up. also just like ebikes - they are what they are eg if it rains you get wet. If you want to stay dry use a car. It stops "mass" adoption but people that use visa also want the credit that goes with it so bitcoin was never going to appeal to that part of the visa market ie be "mass adopted".
Will it go to the moon? better to think it already has - I happen to think bitcoins true price is about $60 but considering it was $2 only a few years back it has already gone to the moon if you believed in it back then. I also think it is still on a strong growth as it has not even begun to fill its niche. So i see it going above $500 in a few years if not sooner. it may never be worth $10,000 but nobody involved with bitcoin promised that. they did not promise $250 but that is where we are.
