LTC bagholders wanted to cash out on 19th.. LTC to fiat is too low so they convert to BTC.. But BTC is already in a downtrend so what are they going to do? Of course, convert BTC to fiat.
In that case, yes, BTC should be affected, but that train of thought is weakly linked IMHO. It is a supposition though.
I don't think it's weak. The only thing holding LTC up is the hope that it will get pumped when it is added to houbi, but at the moment huobi started ltc trading, LTC got dumped. Since LTC hype is over, LTC is back to normal following BTC.
Meanwhile, BTC has been following it's own path after the BTCchina hype. And there's the news of other exchanges getting hacked, blockchain.info problem, etc.
I am speaking English as a second language. I thought peak only means the upward peak, the 'buttom peak' is perhaps called a dip?
I'm not an expert in stock market so I'm not sure
But in my field, peak could mean the top or the bottom and I also got confused with your question because BTCchina pump peak was at march 4
