There's a difference between Bitcoin and shitcoins. Although people say they're all cryptocurrencies, they offer distinct advantages and cannot be compared. Bitcoin is truly decentralized and the only one that can be trusted. Shitcoins, on the other hand, offer nothing but short-term speculation, empty promises, or fragile artificial utilities, controlled by developers, whales, or scammers. Only Bitcoin is the most secure and time-tested, while others just follow suit.
What OP mean by crypto is Altcoin, CAN WE COMPARE BITCOIN AND ALTCOIN? Yes, the early Altcoins were specifically created to resemble Bitcoin, not to replace it, but as of this time, we have see Altcoins claiming to be Bitcoin, though the question is which is better when comparing?
Altcoins are alternatives of Bitcoin, created for specific Bitcoin purpose or diverse utility as we have in the crypto space.
Not all Altcoins are shitcoins, but all shitcions are part of Altcoins.
