Sure, I agree, BTC is going places, and is still going to be around for quite some time. But I don't think we should assume it still being amongst the biggest players in 10 years. A lot of new stuff is coming up that imho looks a lot more promising than BTC. That's why I would rather see someone make a market cap prediction instead of the thousand price "predictions" on BTC price I see every day. (But let's assume a couple of trillion $ for now) ;-)
