2500-3000$ each BTC?
Throwing around arbitrary figures won't get us anywhere. Numbers of where Bitcoin could go after the ETF are generally based on weak speculation. Frankly, it could go nearly anywhere.
If tons of new big time players enter the market it could get silly for a while. Hopefully just doubling the price over the next year would be a more true organic growth rate. But yeah why not up to 10k and back to 2k, who knows.
