What's Your Opinion On This Matter
Actually, it depends on the situation. But I think it will be hard choice. But I personally think that holding bitcoin is better than holding any other coin, if there is a whole bitcoin holding then it will be more better. Why I mentioned the situation is that it would be better to own entire bitcoin by selling the majority of Ethereum coins, but definitely not at a loss.
If ever the situation is such that you see bitcoin at a very good DIP price but then ethereum is at a good price. So in that case I think it would not be good to miss the chance. For example, if the price of Bitcoin is 16k and I have some Ethereum and the price of Ethereum is 2.5k, then I will not hesitate to sell my Ethereum and buy whole bitcoin. But I don't think this kind of situation will ever come easily.
