The process started about 10 days ago, because my company has been bought out I was forced to roll over my 401k. I could have rolled it into a new one, but I was recommend unchained capital to get bitcoin (not an etf)
The process was extremely simple. I had to provide 2 hardware wallets for a 2/3 multisig which was extremely easy to set up on their site. After that it was just a matter of requesting disbursement from my original provider. They sent me a check (made out to fortis bank) and I sent the check to them.
It was deposited, and then like any exchange you just set your purchase. As bitcoin was at $83500, I just pulled the trigger and bought it. I'm sure i could have screwed around and DCA'd it in etc, but honestly I was prepared to get it at $100k so whatever. Now to the downsides.
It's KYC obviously, there's no real way to get around that without paying penalties on my 401k. There is a 250$ annual fee, starting on your 1 year anniversary. Considering how many places use a % based fee I was fine with it. And finally there's a 1.5% fee on trades.
When considering the fact that this is now my bitcoin, that I control with my keys, I'm happy with the deal. It may not be for everyone, but I'd much rather have this set up than a 401k.
Also, it wasn't a massive amount of money, I haven't been putting into a 401k for a terribly long time.
