I'm not too familiar with this to be honest when it comes to crypto. But as a general concept. A fund manager, is basically a custodian of assets.
It's common in the world of traditional investments, so I'm not surprised these are starting to sprout in crypto. Now, it's important to research the legality of these things, because there is a good chance they require KYC compliance and that to me is a deal breaker.
yes i figured it was something mirroring other asset custodians... but did not understand the -sell "us" and the 3-5 year crypto cycle" -- so cryptic! haha would really be interested in more transparent communication, but then i know so many of us would....and thanks!
