Probably not, at this time bitcoin was still on the top so why converting it to ethereum if we are surely 100% to bitcoin that price will rise up. Do you want to convert gold into silver? think about that. Bitcoin still the king so dont lose hope be patient and wait for the bull run.
I think the previous statement made a clear point but I do not completely agree with it. It could be better if you keep majority of your Bitcoin and then convert the minority into different types of alt coins, not just Ethereum so if in case a specific coin drops its value, the others would not be much affected and you would not suffer too much loss.
