Or you may be left holding fiat when bitcoin's price breaks out suddenly.
Ha... nope, I'm aware of that risk.
Before I'd ever SEND any bitcoin to someone (like if they're buying from me) I'd first BUY the same amount.
Then IF the buy didn't go thru for any reason (i.e. like maybe sometimes it's not available at locked-in price, on-exchange?) I wouldn't complete the sale.
That way, my BTC pile would never go down, and the only risk exposure would be if the exchange's locked-in price on that particular purchase didn't come thru for any reason (and, yes, it's a low risk if you're using a reliable trusted exchange source but still, THAT risk means I'd never sell out ALL the BTC I hold!!! Only a portion of it at any one time would be allowed to be "pending" delivery, and the larger portion would always remain securely socked away in long-term cold storage... NOT to be TOUCHED at all!)
Honestly, I'd probably even put that BTC into a cold wallet that only my wife and my attorney knew the password to, so I wouldn't ever be tempted to dip into it myself, LOL... and hopefully my wife wouldn't divorce me and run off with my attorney.
