Gold is really the best investment at all and you can be safe with it as the price is going to keep on rising as the time goes by. And you don't have
need to do some hard efforts just to get profit with gold. The same thing with bitcoin even you are just going to hold bitcoins too as long as there
is a good fluctuation in the market you can still get profit, so I would go for both too.
You are right with it, only people that has able to invest big capital of money are able to avail to invest with gold. But for those people that cannot
attain to invest with gold, then bitcoin is going to be a good substitute for it. It is going to depend on them on how much they are going to invest in it
and btc is very flexible.
I hope you mean to say that we "cannot" get big profit with small investment in gold and that's true as gold is an investment of rich people and not all can afford to invest in gold.
