you need NXT AE for that
NXT dividends for all shareholder daily or weekly
NXT Asset would be an excellent option
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?
I would cautiously buy into the most recent ROM addition WEALTH. This depends on how quickly and how much btc can be raised. At the current rate, smart buys can still be made.
