Altcoin boom must be followed after Bitcoin boom. Since Bitcoin price is in a decrease period, it is difficult to expect another altcoin boom. As you said, we already experienced a Bitcoin boom last year, so this year is the decrease on Bitcoin price (correction phase). As long as Bitcoin price experienced a downtrend, altcoins also follow it. That's why many altcoin prices are decreasing so much nowadays. Next altcoin boom probably happens in the next Bullrun, in 2024-2025.
well, based on experience, once the price of bitcoin rises to ATH, then the following year will be a correction. however, the thing to note is, the bitcoin ATH price is around $60k, and currently the price is still in the $41k range, so I feel that the correction is not as deep as before. even now the potential to go back up to $60k is still pretty big. well, I just hope that in the near future, we can see a new ATH without having to wait for the halving or next year again. but, still, the short-term prediction for bitcoin price could go up to $43k, and if the price continues to rise, it may be as high as $48k. well, it's getting close to ATH, so I hope this continues.
