The more that bitcoin goes up, the more likely it is that money will spill over into the 'alt-coins', thereby increasing the chances of more of these coins.
All of the coins are just copy and paste versions of bitcoin with some parameters altered or changed, and there are people trying to magnify that one parameter changed makes a coin better than the parameter changes of another coin.
If Bitcoin is being successful, then all of the coins are replicas of bitcoin, and all of them have a chance at being successful as well.
If bitcoin goes to $1000, then I think that more people will look for cheaper alternatives to invest into.
Why? Why will people look for cheaper alternatives? Bitcoin is divisible to 8 decimal places meaning people can still invest even if they've only got $50. There's no need to go to altcoins. If 1 bitcoin costs $1000 and Bob wants to invest $50, he just buys 0.05 bitcoins. When the bitcoin price doubles to $2000 four years later, Bob's bitcoin are now (theoretically) worth $100.
The more people see bitcoin success story, the less they will want altcoins.
yeah btc fanbois keep telling this to themselves, but the rest of the world doesn't really want to deal in fractions of btc, and higher btc gets the more dangerous it is to use as a currency (huge swings create too much currency risk, and lets not goto oh but xyz 3rd party site etc solves this).
bitcion success story to most people is purely as a trade tool and the higher it is vs USD the greater its percieved success, yet its next to useless for its original intended purpose.
guess alot of the anti alts crowd haven't actually used alts, cause after using a few alts, btc feels like a painful dinosaur to use.
