Earlier quoted context omitted.
Same is true about Facebook. Someone could clone the features and create facebook2.com, and everyone would flock to it. That's why Facebook stock is a Ponzi scheme. Anyone who thinks Facebook has a value above $0 is insane.
Nope. People use Facebook. People simply don't use Bitcoin for payments or any other use that benefits from its "network effect".
The network effect is extremely strong in the cryptocurrency space. Everything in the cryptocurrency space supports bitcoin, and fractions of everything support anything else. Payment processors, exchanges, hardware wallets, software wallets, secure storage and backup systems, etc... All of it is focused on bitcoin first, and adds others later (if ever).
If you want to buy or sell bitcoin, you've got tons of repudible options, you want to buy or sell monero? You've got 1/3 of the options, and most of them are small and shady or don't deal with fiat currencies in any way.
If that's not a network effect, I don't know what is.
