A dream price would be 100k per bitcoin then pretty much everyone would sell i think, pump it and dump it, dumping 100 btc at 100k usd would be crazythe problem would be how to move the money after, maybe i would just buy a lot of things before dumping it into the market or do a private broker deal for 100 btc at that price.
Well if they all dumped it then the price wouldn't stay at 100k for long, this is why a gradual growth of bitcoin over time is ideal. If we have another sudden spike people will dump it enmasse and then we'll likely just have another burst bubble. We need slow but steady growth and I hope that's what happens.
