Is the market crashing on common single gene snakes? Probably. It's a simple issue of supply and demand. That doesn't reflect the multigene and recessive animals though. For everyone person that joins the hobby, another leaves. People think it's a "get rich quick" scheme or something and they buy furiously and then exit just as furiously when the struggle to sell single gene subpar animals in a handful of weeks. This is especially bad when someone has no reputation, has invested no time into the community, and buys and then breeds anything that's cheap. Like all things you get what you put into it.
