This is big, very big, similar to an ETF approved. You will be able to buy Bitcoin easily, all the computer illiterate boomers that just can't get their heads around downloading a wallet and securing the coins, will be able to get Bitcoin exposure. And they seem to be serious: No shitcoins, only Bitcoin.
meh, this sounds like more empty hype (just like the ETFs). "if you build it, they will come!"
you assume there is all this latent demand for bitcoin exposure that is waiting on the sidelines---why? it's not how the human mind (and therefore markets) work. people and institutions who want bitcoin exposure because of its astronomical gains don't say to themselves, "no problem, i'll just wait 2 years or 6 years for the right derivative security product to be approved by the SEC!" lol. and there isn't much volume in the regulated swaps and futures markets. what makes this so different?
also, it's not all good news. like you said, all this latent demand you think exists is from people who don't understand the point of BTC anyway. we like to think people understand the difference between "real assets" and "paper assets" but most don't. and if there is so much latent demand for paper bitcoins, as you suggest, that opens big opportunities for spot market manipulation, just like the gold markets:
