The idea is in fact the last thing I look at because if there is no experienced team, roadmap, whitepaper etc. The idea is itself useless, just an idea.

Gold is 99% infallible and a very solid investment. This is an asset that has survived and lasted centuries, one cannot go wrong with gold. Bitcoin on the other hand, as exciting as it is, is still fresh and new, and nobody can say for sure what direction it will take. Things could still go pear shaped for all we know, or the opposite could be the case. I think it will do well, but gold is a sure thing. To be safe how about, a 50/50 split.
