If you can spend crypto in your local stores to buy daily necessities - then it is good for you. But not everyone lives in such countries today. In many places bitcoin and crypto are grey areas.

Fiat has its importance of running the economy, you can just be so stubborn to save money in crypto completely which has its own risks. There needs to be a fine balance between saving fiat and saving crypto and this will be governed by what mode is being accepted in your country.

I think fundamentally "good" coin is bitcoin and that is a leading cause of why so many shitcoins actually exist. Because they all try to copy and bring their names to fame from bitcoin - the coin that everyone needs to focus on. So if someone wants to get into crypto, they should use the term singularly for bitcoin and stalk its price for getting a point to buy in.
