Hi to you all,

I know this is quite a stupid question, but I've searched info everywhere and I'm always not sure about the difference... Here's my understanding:

There are lots of blockchains (code), each blockchain has its coin. The coin is the code based on the certain blockchain. Such as bitcoin, ether. The blockchain of bitcoin only can do money transactions, not smart contract. When projects need to build a contract between parties (a platform for freelancers, for example), they use the blockchain Ethereum.

Tokens, are the coins that don't have their own blockchain, they use the blockchain of others to build their program. But, my question is, in this case, why every token's dream is to be the "next bitcoin"? Since they don't have their own blockchain anyway, how could they ever be a coin?

Thank you guys in advance for helping me clear this up
