I think there is a connection between them, because the whole market almost depends on the mood of the BTC rate. Once he grows up, so behind him immediately grows and everything else. It is worth it to fall in price, so he also pulls everyone to the bottom. What to do, that's such a strange dynamics. Until the end of not imposed why so and how long this will continue?
The high volatile market make some traders suffered lost. Have you ever seen a trading platform that not list BTC? First time trading platform must list BTC. Only eth dex platfrom like idex and forkdelta not list BTC. As we know that all coins depends on bitcoin, that is why some whale know how to pump and dump. They have a lot of cash to control the market.
