As Ethereum blows up and becomes the all in on platform for smart contracts and dapp ecosystem....you may want to start "investing" in ENS (Ethereum Naming Service):
This would be like the early days of securing an http domain name. You can still search and hopefully buy a 3character domain (which is RARE) and hope that it will command $$$ in the future. Just think of PS/Xbox gamertag handles with 3or4 characters and see how much they are selling for (10k+)
Look at Instagram/Twitter handles with 3 or 4 characters and they are selling in the MILLIONS.
You can start selling your ENS using opeansea (they all connect via metamask or any other wallet that connects to ethereum mainnet to use).
A peer-to-peer marketplace for NFTs, rare digital items and crypto collectibles. Buy, sell, auction, and discover CryptoKitties, Decentraland, Gods Unchained cards, blockchain game items, and more. Over 100,000 collectibles on sale now!
