I believe bitcoin prices will stay similar to gold prices, staying so stable. Before end of this week we can expect bitcoin prices to beat gold prices.
Yes, both gold and bitcoin are more stable as it is present for a long time, while bitcoin is very new as compare to bitcoin and making its appreciations to match gold. I think when time will pass the bitcoin will become more stable but I think the income that we can get from bitcoin right now we cannot expect it from gold.
Both are good investments as of now but they do really differ at all and speaking of value, gold does prove out itself in how many years since from the beginning of human civilization it does have already a value that bitcoin cant beat even though he could able to surpass gold current value but still people will recognize gold no matter what.
