Total availability of gold : Total availability of bitcoins
Find out the ratio and form a discipline. Invest in either when cheaper and also set a stop loss.
You are good to go. Don't be more greedy. Always get out of expensive assets as soon as they reach the reasonable highs and move your money to cheaper ones.
It doesn't seem to me that gold really creates wealth as opposed to just preserves what you already have. Over long periods of time, it tends to track inflation. Over short periods of time, you have a lot of variability, but at that point you're just hoping to get lucky. Bitcoin on the other hand has more of a chance to create wealth based on its relatively low adoption rate, if you buy in to the idea that it will continue to expand and increased demand due to expansion will push the price up. Gold doesn't have that same advantage, but it also doesn't have the same volatility.
