Which blockchain do you think will become popular in the long run?

Ethereum. they have issue when it comes to large no. of trasection but they are better

Because of its powerful smart contract features and vibrant developer community, Ethereum will remain the most popular blockchain in the long run. Other blockchains, such as Polkadot and Cardano, are gaining popularity and may threaten Ethereum's supremacy in the future. With the advent of Web3 technologies, we should expect to see even more novel use cases for NFTs. I'm looking forward to seeing how NGOs will use NFTs to produce new types of impact and value for their causes.

Predicting the long-term popularity of specific blockchains is challenging, as the landscape is constantly evolving. However, as of my last knowledge update in September 2021, Ethereum has been a dominant and widely adopted blockchain platform due to its smart contract capabilities, developer community, and decentralized applications. Other contenders like Binance Smart Chain, Cardano, and Polkadot also show promise. It's recommended to stay updated with the latest developments and trends in the blockchain space to make informed predictions about future popularity.
