I think not this year because the prices are unable to rise from a very long time.
Can be but there have few more up coming news in this month, you may also know it like, Few EFT are pending for approval.
Specially for Direxion ETF and SolidX ETF.
Another point BTC Dominance: 56.0% last few month all time high. This point also can be sign for another bull in this year with bitcoin price.
Yes anything can be happen in cryptro currency market
ETF will only hurt bitcoin. I do not think that this will bring real benefits to the community.
