I agree with the fact that the Altcoins came to life, only today they are not as profitable to buy as it was a couple of days ago. But you can still earn a lot. The main thing is a good analysis of coins!
with some of the improvements that occur in Bitcoin, it makes Altcoin alive because altcoin is still dependent on Bitcoin.
so if you want to buy altcoins, now it's good enough and in my opinion you need to check ETH.
Ethereum has been to the moon. indeed, if you still want to buy eth now, it doesn't matter. but my advice is better to choose altcoins that haven't yet significant upward movement and of course select altcoin in the top 50 which is obviously very potential.
