In any case, the total amount invested in bitcoin and other speculative, high-risk investments combined should not comprise any more than 3% to 5% of your total portfolio. The other 90-plus percent should be a diversified mix of mutual funds, index funds, stocks, bonds, insurance and other more traditional investments with predictable returns.
The goal, as always, is to spread your risk. That way, if bitcoin continues to boom, you’re in a position to be rewarded with an appreciating asset, and maybe even cash out with a major capital gain at some point. On the other hand, if it goes bust, the net damage will be minimal.
