Yep. That's exactly what I mean above. Investing in Gold has a risk, too. But the risk should be much smaller because the price change of Gold isn't as significant as Bitcoin. Also, Gold investment is always popular every time, it is already proven for many many years. And it is also supported by all parties in the world, including the government. This makes Gold is safer for a long-term asset than Bitcoin, now. However, Bitcoin may be like Bitcoin too in the future. 

Indeed. No investment has no risk.
Sometimes the risks reflect the profits potential. For example, Bitcoin offers potential big profit but it has a big risk as well. While for Gold, the potential profit probably isn't as big as Bitcoin, but the risk is relatively smaller.
