is an open ended contract better than one of the 2year x11 ones?

its hard to speculate on either btc of dash two years time, DASH is the most profitable contract right now

just wasn't sure what the diff was between the two, if you just kept buying more hash power for the 2 year one then wouldn't it also just keep being extended and therefore be just like the open ended contract? not 2 yrs

also if you have gone with a btc contract can you reset the allocation and mine dash instead? or must you only mine btc if you selected the btc mining contract?
