For technical analysing I just follow bitcoin graph , If the bitcoin price rise up usually 99% of the coins and tokens would rise too , no matter it is XRP or ZEC , the only thing that remains is how much they can rise if the bitcoin rises , and I would say it depends on how deep they are and what are the good news about them .
Ripple is totally against in Bitcoin so I don't accept 99% of coins and tokens are follow the Bitcoin. But most are follow the same way so If you think Ethereum is lead the many coins that is acceptable because demands are control the crypto value. Once whales are selling continuously in crypto automatically all the coins are moving to backward similarly.
Absolutly relate to your idea. Its a complex relation between Ripple and Bitcoin, Bitcoin will never be a national or any currency.
