Everyone in this subsection of Bitcointalk is waiting for altcoin season to come again. Some have already given up.
I will try to post my observations about the market relationship of Ethereum which is the current lead indicator of altcoin market health to Bitcoin's.
I believe Ethereum price action to be independent of Bitcoin's value. While it is true that most other altcoins follow the trend, Ethereum is a beast (sometimes) of it's own. We've seen this previously when ETH value soard to $1400 and we will probably see it again when the promised glories of ETH 2.0 and proof-of-stake becomes realized. The problem now really is a matter of time, when will ETH devs delivery on their promises?
Experts agree that the price of Bitcoin has a direct impact on the value of other altcoins and Ethereum is one of them. To verify this, just look at two graphs of the exchange rate - for Bitcoin and Ethereum. The most significant is 2017 when there was a sharp increase in the price of many virtual coins. So, a significant increase in Bitcoin has been observed since the middle of summer, and the price peak peaked in December 2017, when the price reached the mark of 20 thousand dollars.
