I would suggest...both gold and bitcoin.
Damn! you too fast! 
So, my question is, for those of you that actually have good knowledge about Bitcoin and gold, which will you love to invest in, and what is your reason for choosing the asset
I agree 100% with Dr. Beer
do both.
In gold forums you read often of investors playing with cryptos and then putting the gains into gold.
Sometimes someone announces selling gold in order to buy cryptos, but then they get a lot of s**t thrown at them 
The most important part of this story is that when you buy gold you buy bars and coins of which you become the sole legal owner.
Many people think they are invested in gold while all they have bought is some creative finance product.
Next time I will inform before publishing the post

If we go back to investments - I came to the realization a long time ago that mono-investment is a very risky and wrong way. Because it does not provide a solution to the problem of compensation of risks of situational losses.
For example, gold+bitcoin pair compensates well for the "drawdown" of one of the assets, which allows you not to "drain" it by fixing losses, but to hold it until the next pampa (this is to mention the usefulness of bitcoin's wild volatility).
Well, if you have the opportunity, you should expand this portfolio. Real estate is a great option! And it is not necessary to buy a whole "residential complex" at once - it is enough to buy 1-2 apartments, normal layout, at the very beginning of the development and after commissioning - to sell! There are really legal restrictions, in my country, for example, when reselling real estate less than 3 years after purchase - you have to pay a sensitive tax. Therefore, I buy with the calculation of "freeze" for at least 36 months.
At the same time, the profit from such an investment, for example, in terms of dollars - higher than the investment in gold for the same period.
Or for example, numismatics - I have in my portfolio a mixture of my childhood hobby and current interests - gold and silver coins. Less high profit - but it is precious metals, in rare editions, whose value is guaranteed to be higher every year. But this is a delicate topic, there are a lot of nuances. But I like it - and for the soul, and beautiful, and gives income
