Hello, I am worried about Bitcoin And Ethereum future, I can't see any good update which will beat the competition.. Why? Why they can't provide better solution and solve the problem with speed of transactions and scalability?
No need to worry excessively, you can see bitcoin still in the top position and ethereum catch up, it might be a reason not to worry. Solving various bitcoin and ethereum problems is not as easy as you imagine, because it takes time and testing process.
