My favorite altcoins in dollars are now worth less than when bitcoin was worth $ 5,000 for example. I believe, that when bitcoin is growing rapidly, many people sell altcoins to buy bitcoin.
What is that altcoin/ you might have shared with us.
Favourite coins goes to cheap I understand we will find the value goes very low. Please take that coins to USDT or BTC for your future safety.
Now all the coins are operates independently so no need to compare the both alts and BTC.
