Eth when viewed from the number of tokens that adopt it is very promising because it is still trusted and many still have it, unfortunately the high transaction fees are an obstacle for ETH, the large queues in the transaction make the fees more expensive, besides that there is no significant problem for ETH.
The adaption was in full swing until the transaction fees started to spike and seeing the opportunity there are other projects trying to take advantage especially Binance who took the opportunity and ran with the situation and now all the new projects are using BSC rather than using ETH and in the future we might see all the projects using multiple chains in the project as some are using multiple chains .
