The “paper billionaire” argument does not hold: https://github.com/MKorostoff/1-pixel-wealth/blob/master/THE_PAPER_BILLIONAIRE.md

To Nole Skum it is a joke. He has a total wealth of about $270 billion. $250 million is approxinately 1/1000 of that.

So divide your wealth by 1000, think of how you would feel losing that due to a rare event, while you knowingly took the risk. Does not seem like a big deal to me at all.

How does the connectivity work? Is there some sort of Cloudflare-like VPN-ish gateway that they host?
