If you want to convince your crypto-enthusiasts, don't try with a huge report. It's not going to be read in detail (IMHO, just like few people ever read whitepapers). I'd make a short list of your strongest arguments, and have a conversation based on them. Probably even 1on1 if you can make that happen.

If they still want to do it, and you have no voting power, you are basically hosed -- consider though that if your investors do have voting power to sway direction, that's why they bought voting shares, to be able to sway direction. And if that means making non-sensical moves, oh well. And if you can't get your CEO's vote on this, and he can't convince the investors, it's probably a good moment to look for a different place to work at. Your company isn't yours unless you hold enough voting power.
