After the end of bull run in 2021, naturally altcoins get dump and as the bear will still effect in 2022 & 2023, crypto won't pump high or rather more dump in those years. But next bull run is suppose to be done in 2024 even the bull is already going on in my opinion cause btc reached to the ath record already again. But btc halving will possibly start within some days, thats the fact why altcoins could dump again even today market already start dumping. Besides all of altcoins you mentioned are top coins with heavy marketcap and volume. It isn't possible for most of these altcoins to pump 10-20x, but 3-5x is possible in next year if the bull run started. Your getting over hyper of those, but in reality, there is less chance of those won't hit such high as you predicted
high increases are common with new bitcoins. for altcoins with large capitalization such increases are rare.
The impact of the Bitcoin halving may not be felt in the near future. a decline has occurred and perhaps a pump movement could occur at the end of the year or even at the beginning of next year.
Let's wait and see what happens in the market, but in my opinion even if there is a pump on Bitcoin and Altcoins, it will not bring an increase too high.
