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.
