Domain name speculation
Domain name speculation is the practice of identifying and registering or acquiring Internet domain names as an investment with the intent of selling them later for a profit.
The main targets of domain name speculation are generic words which can be valuable for type-in traffic and for the dominant position they would have in any field due to their descriptive nature. Hence generic words and phrases such as poker, insurance, travel, creditcards, sex and others are attractive targets of domain speculation in any top-level domain.
