There is a reason why gold is better than bitcoin. the gold price tends to be more stable, while the bitcoin price is fluctuating. So investing with bitcoin is high risk when compared to gold, but if bitcoin prices are rising then it will produce enormous results but one day can go down drastically too. And one more gold can be used for long-term investment although any change in price is not too significant.
You just compared by now, what do you say when you buying 1000
BTC in 2010 and 1000 gold in 2010, and now 7 years later
BTC price has been increasing much multiple times, how much gold increasing price?
This is how people interesting to invest on it. You can see on some trading market else Crypto, such as Forex, stock trading, etc. they have same fluctuating price condition, it is become common thing. You need strategy to making decision when to buy and sell.
