Every day that Bitcoin's dominance rises or at least stays at this high levels shatters the confidence of altcoin holders - I visit /r/cryptocurrency from time to time and they are so depressed at the moment.
It is time to accumulate more good altcoins. Let's recall what happened with bitcoin and bitcoin enthusiasts in 2018? All or most of them depressed as same as altcoin enthusiasts now. I do think altcoin enthusiasts can learn from the very recent lesson from bitcoin. Unfortunately, if they hold bad altcoins, they should stop dreaming for aforementioned reasons (in my previous post).
They should know when to stop hoping without convincing reasons, and when to cut their painful losses from past wrong investments.
