Great info. Any adaptation is good news.

Based on the comments I think this may be an overlooked point:
"While any of us can use exchanges, huge investment companies need proper funds with all legal work and need to use "wallstreet" or in this case NASDAQ to feel safe with huge investments and be sure that exchange wont disappear."

For those wondering if their IRAs and brokerage accounts can trade this, I would ask you one question, how much exposure do you have with direct ownership already?

While this may be a method to gain a initial position in crypto, it's hardly ideal as there's no transfer mechanism to other products. What if ETH is overtaken by a competitor, or if the ETN picks the wrong side of a fork? Do you sell the ETN into fiat then wait for another ETN/ETF as you sit on your loss?

If you have a reasonable position in wallets or on the exchanges (note: you may want to have both across multiple accounts in mitigate risk) why would you add that to your retirement portfolio? We don't know who will win the horse race, but we do know (or think we know) that blockchain will in some way be integrated across several uses. And if this is the case, then we know that the infrastructure will need to be built out. There are several current trade-able options that have a much, much lower risk such as GPU producers (that ship may have sailed), retailers, processors, etc.

These products are for the "b" team. Those that can't figure out how (or are too lazy to learn how) to get money into the ecosystem. And for that, they trade at a steep premium.

It feels like an unnecessarily risky proposition if you already have a moderate investment in the system. There are still those 10,000% returns out there. You just need to do the work and with a little luck, you may stumble across a couple. And if you don't have a position? Find a faucet, dabble in mining, curate a board. $1/day is a lot if you stumble across a lottery ticket.

Good luck, I hope the good guys win this time.
