Both are assets, nothing to compare here. Just like bitcoin is a good place to invest, gold is also a good medium to invest. But gold has been reigning for a long time. Whoever has a large amount of money to invest, he must invest in gold, because gold is nothing compared to gold. but BTC is very reliable way to invest. There is no risk of losing money. It's a little long time process and you can invest as much money as you want. You don't need huge amount of money to invest here. Expect BTC investors to gain more after the bull run.
I don't know how important gold is for investment but I think Bitcoin is the best. As much as I think it is better to invest in Bitcoin instead of gold. I think only people who have no experience with Bitcoin will want to invest in gold.But those who have experience and know about Bitcoin are sure to invest in Bitcoin instead of gold. Like you I am investing a little bit in bitcoins and I am investing through dollar cost averaging (DCA) every week. My invested bitcoins I'm not thinking about selling yet My invested bitcoins I want to hold for a long time and I will.
