BTC is very close to breaking its past ATH record in the current bull run. Don't you notice that not only the BTC price has increased in the current bull run but also the alt coins. The ongoing bull run has seen many reap more profits from altcoins than they expected. My personal choices among the best alt coins to focus on are ETH, BNB, SOL. Although I am not invested in BNB and Sol, I am invested in Ethereum. With the price growth currently observed in these alt coins, I am optimistic that they may surpass their past ATH in the next bullrun. However, I take my own decisions in my altcoin investments, if you want to invest in altcoins, you should definitely give priority to your personal decision.
