I don't choose one out of the two, and my reason for purchasing any of them would totally be dependent on my financial goals and targets. If I'm looking for quicker profits and ready to risk my money, I would go with Bitcoin, even after knowing that though I may not lose my money but it can get devalued for years if the cycle restarts since I will then have to wait for the bull run so that the market can actually recover back to the point where I've bought.

But, if my goal is to just get steady and long-term profits without the fear of losing any value for my investment, I will definitely go with Gold since I know its a more stable investment and will surely give me some returns after any period of time if I wish to sell them unlike Bitcoin which has cycles.
