I think, the time has come for more "mainstream" in the crypto market.
it is called bitcoin market not crypto market.
the fresh money comes in only to bitcoin, because it has been around for the longest and it is the most trusted thing around. outside of bitcointalk (or generally crypto circles) you will never hear anything about "altcoins" if you say the word altcoin to someone they don't know that the hell you are talking about but if you tell them "bitcoin" they have at least heard the name before.
and all the investment part of it aside, there is only real world usage for bitcoin. you can see it actually be used as a coin or currency. and you can never say the same for any of the altcoins except some random small shop on the dark corners of the internet accepting a random altcoin that nobody ever used.
You are describing the status quo. Not even the trend.
And what the future will bring - we'll see...
