Do you remember when the iPhones were out? I remember that it was the first digital smartphone i saw in my life, Some people till now adopted the name iPhone for smartphones even if it is an HTC or a Huawei, Because iPhone revolutionized the world when it came up, But This doesn't mean that Samsung or Sony aren't great, they share the mobile market altogether.
This is a small example that adapts for Crypto, Why bitcoin is famous and has a high value? because it's simply the first one, so it dominated the market alone for years, Now DeepOnion and others projects might just be like Sony and Samsung.
