Well, we all have different opinions and expactations from crypto.
From my dexperience, when bitcoin grows alt coins grows even faster but when the bitcoin fall altcoin falls even faster.
I had some funds before invested in alt coins but I decided to move everything in bitcoin in order to preserve the value of my portfolio.
This is answer based on my experience.
If you monitor the only top 10 altcoins your decision was write. But currently we have many altcoins in crypto market so I see different types of falls in Bitcoin and altcoin. If you like Bitcoin it was your own decision but you complain the altcoins many supporting peoples available in this forum. If we concentrate our own decision that will be a good movement in any transfer.
That is true. I have been witnessing the same trend of rise in the prices of Bitcoin and altcoin and the fall in the values of both the coins when the market is going into recession. This is normal for assets in crypto market. Altcoin loose quick value because where we face a loss of $600 in the value of Bitcoin lets say from $5000, a similar loss in ETH could be more than 80% in case in case it falls from $600 to 200 dollars.
