People don't realize just how big web3 is about to become. It really is going to take the internet as we know it today to another level. The term Web3 is now being massively mentioned particularly in the media.
Again it's all about the keywords. Willy nilly keywords won't work. They have to be sensible to Web3 and domain syrup has some excellent ones.
The best Web3 domains are taken and I feel that there will be big domain sales related to web3 soon.
The best web3 domains in my opinion are:
Web3 + Browser (obviously)
Web3 + Wallet (massive part of web3 infrastructure is the web3 wallet)
My Web3 +Wallet ( my nft, bitcoin, eth wallet domains are hot and will always be).
Web3 + Coin(s) (great domains and obviously so)
Web3 + Applications (great domain and perhaps the most relevant along with browser, wallet etc, it's all about web3 applications and startups across the web3 industry are focusing on web3 applications)
Web3 + economy ( the term web3 economy has taken a life of it's own and has become synonymous with Web3 and its applications)
Web3 + creator ( great domain)
Web3 + development (obviously so, great domain)
Web3 + news
There will be several other web3 + kw domains that I have missed but I feel that the above are amongst the best.
