also i would love to choose bitcoin but if i have large amount of fund, i didn’t invest full amount in bitcoin, i will invest some gold because it’s 100% safe assets, and then i will invest in bitcoin it could be long term or short term, if in online security is a big issues, it’s not easy to protect online currencies, so without good security knowledge you can loss your money.
I see the issue of security as a minor and should not be seen as a reason for not investing in bitcoin or other online currencies since there's no maximum security guarantee nowhere. It is good to always diversify your investment but when comparing between these two (bitcoin and gold), the former seems to be advantageous over the latter. Bitcoin is open to all irrespective of where you are so long as you have access to network and wallet but gold is easily accessible for everyone to invest. Mind you, no asset is 100% safe for investment, there's risk no matter how small it is. Remember, the higher the risk, the bigger the profit but you need to play smart.
