Learn Go or Java for future

I'm 22 grad 2 years and few months of experience 1 year in python and 1 year in c#. So I am comfortable with both paradigm of coding. Those design pattern ones which are used in java and dynamic type coding with python and ruby.

Since there aren't much jobs in c# should use my same knowledge and build my experience in java and projects too so that in future I can get good pays in java I have seen legacy or big companies paying good for java.

Or should I learn Go, fairly new and exciting and seeing many openings of Go these days with good money

Suggestions?

P.s. I'm looking for opening if anyone is hiring or referring backend dev with ~2.5 yoe DM please
