Both ethereum and Bitcoin are at a stable price right now, ethereum still maintained its almost 4k price and bitcoin rely on around the 50k region but those investors looking for quick profits are looking for better options between the two so should one remain with Bitcoin or should look for another option like ethereum so what will you advise for a new investor.
It's not really "alternative" as they have build something completely different from each other. If you are looking for upside, you should look at the marketcap, and that has way more room to go then bitcoin. After eth 2.0 really starts to have an effect with speed and cost, eth will most likely flip btc marketcap. Before that it's just gambling with a coin that's too expensive to even use.
I doubt ETH will flip BTC marketcap seeing that only a few institutions express their interest in ETH but there are speculations that ETH will rise up to $20K. It will be hard to see that ETH will be on top of BTC because of its total supply which if they are going to move to POS soon, there will be a chance that it could trigger a bear market. But this is still just what they are specaulting. If memory serves it was in the Savvy Finance youtube channel that I heard of it while BTC will go going to $250K.
