for 3 or 4 or even 5 years, I can invest in Bitcoin with peace of mind that it will over perform Gold, but 10 years is a very long period that no one knows what technologies will be available at that time that may shake things up.
i think investment for 3 or 4 years in bitcoin will be a good investment. we can expect that after 3 or 4 years bitcoin will give you a very good profit, which we cannot expect from gold because gold is so much stable and may be very little increase are decrease in its price after years as compare to bitcoin. i think gold is good but for saving, but now people are not interested in saving their assets in gold because security of bitcoin is also a problem, and keeping gold in banks is so expensive therefore investment is the best option.
