In my opinion, the best coins to buy besides bitcoin include Ethereum and BNB. because both of these coins are very good and have the potential to make a satisfying profit. moreover the price movement is stable. And I'm sure if you invest in these two altcoins, you will get a big profit.
I see the current market conditions that are still very potential and have a safe point for trading only in bitcoin because we all know that bitcoin will experience price increases due to the influence of halving which might have a good impact on the price of bitcoin, whereas if trading for my altcoin see still have a very high risk of loss that can befall you.
