I just want to acknowledge your concerns, comments and time to share them because many of the points you make are ditto for me, although I already own a handful of niches to get in early. I cannot comment or clarify your points as I'm new, too, but I'm eager to hear from @Malkazoid and @David Dreezer who seem to have the major pulse of this platform and community. So, thanks for putting it all out there to open discussion.
My experience with buying NRVE failed due to a bank issue and a freeze on the account, so I had to use a credit card as a niche was due for payment. I spent an entire week on that experience only to end up with many new accounts and a lot of anxiety over cryptocurrency!
