Thanks for your analysis.
Could you please get back to Coin vs BTC please ?
Coin vs Dollar is completely meaningless, as it is mainly tied to the price of BTC itself.
When altcoins are traded, they are mostly against BTC, so that's where the analysis is really relevant.
We can all assume that most altcoins are going to rise in USD if BTC itself is rising.
The real "index" currency for altcoins is BTC, not USD.
Cheers.
