Exactly. However one day altcoins will not probably move with the BTC exchange rate, i hope. I think that this was just another bubble like in 2013, when bitcoin moved all the way up to 1000$ and then dipped back to around 100-200$ rate. However since bitsend price is so low right now, that just means that it makes a great investement considering the motivation of the team and the tehcnical aspect of the coin. Like i have mentioned before, Bitsend has huge potential considering that there are alot of shitcoins with much higher market cap and price.
in crypto-ecosystem, all altcoins are under strong impacts of Bitcoin movements, so it's not strange to see all altcoins plummeted due to Bitcoin dramatic falls recently. There are lots of FUDs recent days, which in turn lead to deeper falls.
