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.
Personally, I see no reason to sell BTC in order to buy ETH in return. If you have already bought BTC, then it is better not to sell it, but also buy ETH, then you will own two promising cryptocurrencies. But if you would like to have one cryptocurrency, then in my opinion it is best to leave BTC, since BTC in my opinion has a better chance of increasing its price in the future. However, if you are a pro in cryptocurrency trading, then you should probably sell your assets for a while and buy those that are now showing a lot of price volatility, which will allow you to make a big profit.
