Agree bitcoin is much better if you are risk taker but if you want is safest investment is you would choose gold.
But me i choose to hold bitcoin because it has a big possibility to make me rich in a few year by doing investment which you can not get in gold.
if you risk taker certainly you will buy altcoin rather than bitcoin, bitcoin buyers just play it safe and do not want complicated while gold only for investors who do not know about technology.
