Bitcoin has really established itself now.

It's the coin that has shown to be solid, has a solid network and security, doesn't have questionable teams behind it, is more than decentralized enough, and the coin people trust the most to work.

It's solid, when it comes to holding your coins digitally like gold.

But it's not the end all answer to all crypto problems.

Other coins and chains that will still be needed:

1- A fast and cheap point of sale crypto.

There will still be a need for a coin with fast and cheap transactions, that's scalable, with a chain that can handle heavy traffic. Something easy to integrate in point of sales systems, that's easy for buying a coffee.

2- A dev chain.

A blockchain built for developers, that's more ideal to build on, with smart contracts.

3- A business chain.

Similar to a dev chain, but more business oriented.

4- Industry specialized chains or projects.

Some industries like real estate, medical, scientific research, social media, gaming, etc.. may require a more specialized chain for their industry. Just for a few cases where a dev/business/trilemma chain may not be enough.

5- Chains or projects specialized in a specific tech feature.

These are your chains or projects specialized in a key tech solution like oracle, indexing, interoperability, IOT, AI, etc...

6- A trilemma chain.

This will be your swiss army chain. The chain that solves the trilemma and is strong enough at security, scalability, and decentralization.

Coins and chains that won't be needed (probably 90% of what's out there):

1- Any chain that's not doing something new or doing something other chains are already doing, and not even doing it better.

2- Any chain that's doing something too centralized.

3- Any chain that's not solving a tech problem, a lifestyle problem, a business problem, or an industry problem.

4- Any token where the token itself is not needed in the system.

5- Any project with too much control from a team, or a poor team behind it.

6- Anything that's not bringing something to the table.
