Earlier quoted context omitted.
Bitcoin is currently the crypto equivalent of gold. It's not reasonable to use it to buy a coffee. However, Bitcoin is trying (but many would argue, failing) to upgrade the network with something that will allow cheaper/faster transactions and make it a reasonable currency again. However, (imo) in-fighting has seriously hampered this. That being the reality, many people hope that Bitcoin will remain a store of value…
It's not gold. Gold has a long history of being a stable store of value. I could buy gold now and sit back and not worry that the price was about to fall through the floor. Owning bitcoin is not the same. At any moment it could tank. If all the investors suddenly got interested in Pokémon cards they would be just as useful as a store of value.
Lots of people have believed that in the past. Sometimes they've been right, sometimes not. The future supply of commodities doesn't always follow expectations.
