Bitcoin drops sometimes it's not a bad thing. What altcoins are you holding? if you haven't sold them yet, you won't lose anything just hold your time and wait for the bulls to arrive soon. Don't panic and get discouraged, this is the normal thing of cryptocurrencies. The market is going up and down and it is falling so it will rise again after that.
We don't need to be sad or depressed if we hold the top altcoin because the decline is only the effect of the Bitcoin price, but I'm worried if we hold the new altcoin because it is not guaranteed to recover the price even the project can be abandoned at any time without the consideration of the team.
