Of course yes, look back on the past days. This entire market has gone up and altcoin has grown along with bitcoin. But it is not always possible, sometimes I see only bitcoin growth and the entire altcoin collapsed. It all depends on the overall situation of the market
Yes, the situation of the market is completely compared to 2017, now the market situation is completely different now companies and people are matured completely different, only active and potential coin with active volume and active developments will help the coin to increase their prices not all the altcoins.
If the price of Bitcoin rises, then this market will enter uptrend and at this time both Bitcoin and Altcoin are rising together, so this will be a good opportunity for you to invest now. People are feeling more optimistic and this reason makes investing easier. I usually just prefer to invest in the top coins in this market because it is more than enough for my long-term profit at crypto.
