For what its worth, if you tried to cash out $800k today I think it would take some time to clear. The paper value of Bitcoins is grossly inflated over the actual market cap. It's a natural reaction to the inherently deflationary nature of the currency, everybody wants to hold on to them because they're only going up! This restricts supply and causes the prices to go up even more. Unless you can buy goods and services (more than drugs and burritos) with Bitcoin directly the wealth is a fantasy.
