BTC + volatility + altcoin analysis - big move immitent

BTC will very likely test once again 10500 and probably even further towards 10800. But one thing has changed at 14th February -> altcoins finished their long corrective uptrends and their main trend (downtrend) should take a lead. But there is one problem - altcoins are dropping ONLY if btc is dropping either. So it´s pretty obvious right now -> BTC must go to deep correction (probably to 8000) and altcoins with btc pairs will go to the all time lows. BUT there is also other scenario, less probable, but still it would make sense -> BTC will pump very hard and money from altcoins will be transfered to BTC.
On the right, you can see chart of volatility. I pointed out all recent spikes in volatility and specify, what happened in each spike. Volatility is squeezing and big move is only matter of time, probably in 1-3 weeks. I think this move will be to the downside.
