Coin vs Token
Not everything that glitters is a Coin.
Coin = own network (#Bitcoin, #Ethereum)
Token = operates within someone else's network ($USDT, $SHIB on Ethereum)
The difference is like between a dollar and a gift card for a dollar.
Both work, but in different ways.
Idea for visualization:
Table or icons: on the left Coin with symbols $BTC, $ETH; on the right Token with symbols $USDT, $SHIB. Labels — "has its own network" / "depends on someone else's".
