I don't like any of the ones that end in gold. It is not gold and I feel it is disingenuous.
Don't care for Moola as a prefix either.

I like the endings bit and coin (bit might be preferable because there are going to but a crazy ton garbage altcoins that end in coin in the near future)

You might want to consider the .net names. They may open up some additional alternatives.
You don't need a .com or .org name to succeed.

Just look at minecraft.net

I also like the .net domain for cryptocurrency because the net is what they are all about.
