I think it is a better measurement calculating Monero's value in USD for example. Bitcoin does not yet have a stable value.
If Monero's market cap remains 10 million USD this year, but Bitcoin goes to 10 billion USD. Does that mean a lower low for Monero?
BTW, (a maybe naive analysis follows) I think that ETH and BTC are direct competitors (like XRP & BTC in the past) but on the other hand XMR & BTC are more of a good pair.
I mean, it is of XMRs best interest 1) BTC adoption to increase as much as possible and people use XMR as laundry, 2) XMR should not become No1 to draw attention.
There is an interesting paper somewhere in the internet on how the Alpha male and the lowest ones in the pyramid suffer the most stress.
The best position to hold is actually No2, all the stress at No1 and you still enjoy big rewards from being the second in rank.
Who would you rather be, Putin or Medvedev?
On the other hand (win win for XMR) if Bitcoin goes bust, XMR is the next most logical substitute for it (in terms of store of value, decentralisation etc).
Actually it may be best couple with ETH (that will most probably become the new King) than with BTC.
That said I agree with Anonymint that Monero is not at all perfect but good enough. Regarding his fundamental analysis on the other ones, I won't argue but there are a LOT of worthless stocks that are not
Good point, I am indecisive at this yet .
Regarding the Alpha male and stress paper, I definitely think Monero has benefited from basically existing outside the pecking order for some time. It gave the devs time to study the stress of Bitcoin and find long term solutions:
Interestingly, the Cryptonote whitepaper already mentions a lot of deficiencies:
