So my first question is... can we really expect another 2-3 year bear? It just seems so unlikely considering the momentum we now see...
Not at all. Can be 6 months maybe even less. It happened same in 2013. bear period after first bubble was short. But we need not to forget that longer time we are in bear trend, stronger Bull trend will be. So if lets says bear trend started now and will end in half year, I dont really expect next bubble could reach $20k.
Monero is the only cryptocurrency I see use besides bitcoin. Future looks bright.
if I correctly understand, then monero is the most anonymous crypto currency at the moment? Or is there still?
Monero is and was most anonymous crypto of all from first day of existence. Only moment that ZCash come head to head with Monero was ZCash launch. But that ended few months latter. I dont really know exactly how long right now. Until the first Monero hardfork after the ZCash launch. Even is we forget that ZCash is a centralized company and trusted setup was needed to launch it.
