You can say that. Because the first BTC, holding market prices, has many communities, many believe. but it is not something that is not possible at one time BTC will be replaced by another, but for now people still put trust in BTC.
WrongHow will another
convince everyone in bitcoin that their shiny new coin has
real value? They won't. EVER.
How will a new coin somehow have a better development team, when bitcoin has the best developers in the space?
Altcoins like Ethereum, Monero, Litecoin have people who are
as good as bitcoin developers but that doesn't leave any talent for "new coins" to hire and somehow create a "better" coin.
The
worst developers in crypto
"try" to create valuable coins and fail. The
best developers in crypto join the
best crypto currency development teams that bitcoin, ethereum, litecoin, ripple, stellar have created.
Starting a new team to create a new coin requires so much capital that it would automatically lose value because questions of the teams intentions will always be asked when looking at a crypto currency. Satoshi and bitcoin don't have that problem.
The Core teams ability to keep the protocol running, secure transactions and store value is not EASY for someone else to just do it better.
