Really difficult to choose only one of the two.
But if I only have to keep one for the long term, I will choose ETH.
Ethereum is at the origin of many projects and the roadmap seems very interesting to me for the years to come
In my opinion, I have no doubt on ethereum that this project will going strong in the future. Actually it is also good for the long term which if you can notice these days ethereum is offering a nice move in the market. As long it is decentralized ethereum users will stay in this project. Though in BNB it is also good to invest but I’m more in ethereum that can give a return of profit in the long run.
