You are only allowed to bump your thread once within 8 hours (rules here). As for the name, ~200M+? It is also dependent on whether or not it has a meaning e.g. "Hi" and not "7g".
For something like that it depends. It is a random word but it's also a first person word which will be popular with stakers and dice hosts etc. I'd expect a range in offers for such a 2 letter name. They are very well liked. Some people will buy ANY 2 letter name just to have the sense of individuality. You will get a lot of good and bad offers for the name so take your time selling.
