You have to understand that just money alone cannot buy citizenships and these countries have stringent rules. When you apply for their citizenship by investment programs (CIP), you have to undergo strict background and due diligence checks done by these Governments. So criminals, terrorists or offenders can never get their hands on these citizenships.
Besides, these CIP schemes, there are residency (a.k.a golden visa schemes) offered by several countries in Europe against a business or real estate investment. You will be given residency, but have to live for 5 or more years to naturalize for Citizenship. Portugal is the most popular one.
Belgium - 350,000 euros (5 years for citizenship)
United Kingdom - 2,000,000 pounds (5 years for british passport)

Before you jump to applying for such citizenship schemes, you may want to investigate the issue of Dual passports. I am not sure about your nationality but your home country may not allow you hold a second citizenship (eg. China, India, UAE, Russia).
