Should I move $$ for college from credit union money market to Vanguard money market?

I just moved to Citi at 2.21 when CitizensAccess dropped theirs from 2.2 to 2.0.

They were 2.35 and 2.36 not long ago, so th8ngs are always changing.

Realize that 0.1% on a $50,000 account is $50/yr. Consider whether it’s worth the effort of chasing tenths of a percent.
