Thanks for your informed analysis on the matter. In fact i have been having a hard time wrapping my head around the fact that some altcoins i was watching, were doing badly or not showing any market response against bitcoin's steadily rising price...
Your post helped to clarify it finally for me. Truly, if bitcoin is less volatile we will see more growth in altcoin trading...
Its only normal if some altcoins still perform well while majority of them are not doing well; there will always be exceptions to the rule.
On the whole, well done!
