Bitcoin is Bitcoin. But since it is a strong digital asset like gold or apartment, it can be called future digital gold.  Bitcoin will be very valuable in the future even though Bitcoin has already become very expensive.  Bitcoin is already very trusted though. But still only a very small part of the world's population is using Bitcoin.  So a big challenge for Bitcoin is still to increase people's trust in it and make at least 50% people vulnerable to Bitcoin. Then Bitcoin can successfully become digital gold.
