Bitcoin will not have the most apps, will not have the most developers, will not have the most traffic.
However it will have the market cap simply because Wall Street deems it so. It has the liquidity and the ROI which is what Wall Street looks for. Sure, you wont be buying a cup of coffee with bitcoin but you might pay your overseas supplier $50K with bitcoin. For transactions like that, it is ideal.
By the time people go about looking for a new "gold" bitcoin will be so entrenched that there will be no point...
Just like gold today, we dont look for another metal to replace it...we just accept it.
Bitcoin will end up doing the stodgy stuff like storing of government records, handling educational materials, etc.... It might still handle the larger transactions but it will never be fast enough to be the everyday currency. But it will have plenty of money invested in it which will keep it propped up.
Point taken. Perfectly rational to say by the time people go about looking for a new "gold" bitcoin will be so entrenched that there will be no point, the only exception I see to this case being something that's already well established in the space with a similar use case of bitcoin takes gets adopted by Wall Street - litecoin, for example, which is in the top 5 in marketcap , widely accepted among every other exchange and wallet provider.
