I don't see how you can make stable profit from ROM yet. We don't enough roms out there pick from only two of them. Are you buying into the existed one or new one?
There is possibility to make profit from ROM if you are having enough buy potential in your hands, if you keep the market rolling others will buy too. It requires a lot of BTC because you have to control a big percent of a ROM coin but once it is achieved it is not hard to achieve a stable profit with self buys
there is a chance for this to work since this rom has low total supply but still many investors in your plan needed
