If you were going to invest in both BTC and ETH what percentage would you put into each? At the moment I have 100% in BTC but am thinking of diversifying.
Are there a couple of others that you would suggest should get some of that percentage, such as DOGE or something else? If so, what percentages?
Doge I would exclude it a prior, if you ask this question it means that you do not know the project and you cannot compare it to Bitcoin or Ethereum.
Having said that I would say that Ethereum has a much larger and more complex ecosystem so in my opinion in terms of value it should be greater than Bitcoin.
In addition to these two, I suggest you deepen your research on Cardano and Polkadot.
