Only coins that do things will be valuable.
That's the important point
Smart contracts are the future and Platforms that have the most active developers in creating applications
with significant utility for their users will have a bright future
Invest in use cases not just because of the speed and cost of using them. IMO
yes you are right, in the end the coins that survive are the ones with the biggest real use cases. and the smartcontract platform is one of the concepts with the largest usage, ethereum, bsc, tron, Cardano, Polkadot, and EOS are the top-ranked coins. they have something in common with each other, namely the smart contract platform. so if you want to buy a long term coin, it's better to buy a coin with a concept with a large use. it will remain valuable for a long time.
