I think you might be worrying too much about cashing in on garbage while forgetting there's virtually nothing from the dev team regarding replay protection, not to mention all the other concerns surrounding BTG including a PRE-MINE.

The dev team is currently pre-mining the ever-loving-crap out of BTG (they say 1%) and quite likely dumping it and cashing in as they do so.

I do like the idea of using Equihash but BTG seems to be a poorly veiled attempt to get rich quick and the market price dump seems to agree.

Get ready for a flood of BTC forks and dumps.
