I consider that a good investment at all valuables including gold. As well as real estate. You can buy houses and apartments abroad, and lease.
I don't think it's a good idea to invest your BTC in gold. By doing so you will leave Bitcoin which is the future and will join (or rejoin) to gold which is the past. To trust in Bitcoin more than in gold is risky, I know, but that is what most people here are doing, and I'm among them. I hope we will profit in the long run.
Everything you said are a good investments, the question is when will you buy it? A good investment needs time in order for it to grow. You won't buy a land that is already at the top of it's market value, you buy it when you know it will appreciate more with time. Also you missed the chance when Gold is at its lowest. I must say you need to look for another kind of investment such as the stock market.
