I think these are 2 good choices, gold and bitcoin are 2 profitable investments but there is a difference, gold is suitable for long term while bitcoin for singular length.
I see these arguments re BTC and gold so often I decided to crystallize my thinking into something seems short yet pretty general and reasonable:
1) If you are young and technically knowledgeable, go for large (relative) holdings of BTC and just a little gold.
2) If you are older, buy more gold than BTC. Fewer years to make up for any losses...
3) If you are within "young vs. old", buy proportionately.
That should do it. (I am older, so have much more in gold and platinum than BTC, but I still have "skin in the Bitcoin Game").
