My personal opinion is that Bitcoin is better for an investment of 1 month today. The whole thing is that he too domains over cryptocurrency. Let's say if Bitcoin grows up to $ 10,000, you can quickly sell it and transfer it to ETH and get even more profit. As I saw ETH, it does not respond so quickly to the growth of Bitcoin.
right, altcoin is currently unable to match the movement of Bitcoin so if we have Bitcoin, it will be more profitable.
moreover if the price of ETH falls then it is a good opportunity to exchange Bitcoin to ETH so that we can get greater profits if ETH rises again.
