Both
For me i prefer to choose both of them as my investment because gold is safe investment and bitcoin because the price is rapidly increasing .
I think gold or bitcoin it's all a good investment tool, you want to choose which one is good. just follow your heart. but if I myself choose bitcoin as an investment tool today. if my gold has never been.
Actually I am amazed with both of these two investments. Both are amazing in their own kind. People are getting in bitcoins and people are getting in gold as well.
Now a days, as the world is going toward the technical side, people and investors are more likely to tend toward the option that is technical enough to make their lives happy and wealthy. So bitcoins are preferred over bitcoins.
