What did you mean Altcoin to the moon, the price or the technology ??
Because altcoin is not start yet to getting the moon of price, and still keep in standar of price.
I believe in 2022 altcoin will blow up and hit a moon after Bitcoin moon in end of 2021.
That my prediction.
to the moon shows high prices, so I am sure that this is a matter of price. however, this is still preparation. I am not sure that we need to wait for 2022 to see the pump price. Let's start speculating at the end of this year, and in 2021. These are tense times for coin holders.
