The S&P500 Market Cap is 24.30T. Bitcoin's market cap is $184 Billion. Therefore for proper hedging, you should put 0.75% of your assets into Bitcoin. For every $100k, that's $750. Put it another way, you should put 132x more money into stocks than you should Bitcoin. If Bitcoin were to steal market cap from the investment markets, you'd be well positioned for transition. If Bitcoin were to become worthless, you'd still be well positioned. Bitcoin will one day become worthless but it may be a while before that happens. The speculation is whether the new universal currency will kindly be available to prior bitcoin holders as an airdrop or fork, or whether it will be a brand new cryptocurrency without any ties to Bitcoin. So far, no cryptocurrency has overtaken bitcoin and the next 10 by market cap don't look like they will overtake it soon. Planning for the additional (and painful) tax complexity in advance is advised. If you don't how to do taxes yourself, it won't be fun to pay an bitcoin-specializing accountant $300-$800 each year because you bought Bitcoin once.
