I'd also choose bitcoin...
The whole market is way more accessible and easier, which makes trading manageable for most of us.
At the very present time if there can be something which can help you in having some good amount of money, then that is one and only bitcoin. Gold is having a stable market value since a long period of time and that it is not helping you in having some good profit. However, if you will go for investing your money into bitcoin, this will really help you in having a handsome amount of profit at the end.
