There is no denying that LINK's first mover advantage in Oracle space, amplified by the DeFi gold rush, has resulted in its tremendous surge recently.
Another reason is that many of its competitors such as BAND, TELLOR, DOS and NEST can only be traded on Dex (decentralized exchange), centralized exchanges such as Polonix (who still use it?) and foreign exchanges that don't take U.S residents (Binance and many other obscure exchanges)
That changed today when Coinbase added BAND! With the increased liquidity and exposure, I ams sure people who are eagerly looking for the next LINK will not miss it.
