What nationalities are barred from seeking Bulgarian residency/citizenship?

Is Bulgaria’s RCBI open to everyone? Are certain nationalities ineligible? Can stateless people apply for residency/citizenship via investment?

On Alexander Dobrinov answered:

Bulgaria doesn’t discriminate any nationalities in its citizenship law, including in the citizenship-by investment program. At the same time, however, certain nationalities may be declined access to financial markets, so they may face serious difficulties in making the required investment.
