It looks like the worst time to hold any alts at the moment , every bitcoin movement up or down creates a sellof for altcoins including monero.
I think it was good to hold alts previous year. Many of them (including Monero) made a very big move upwards and bigger gains then bitcoin. Then after the crash a lot of people went back to BTC so it has lost the least in percentage. So in my opinion it may be good now to start buying alts again, especially good ones - which Monero definitely is.
IMO BTC has the biggest utility at the moment, which also reflect on it's price. I think that it is completely possible that Monero is on 2nd place - mostly because markets on deep web.
When the alts got attention of the people again?
Probably when Bitcoin will raise again...
