If you come across any information on receiving more cryptocurrency if you drop small amount, that’s an obvious scam. Regardless of where the information I published, it is a scam as there is no way of actually getting free Bitcoin without doing anything. On the other hand, you can earn Bitcoin by solving puzzles. The Bitcoin you receive as payment will depend on the number of puzzles you solve. This is a very competitive way of earning Bitcoin unlike offering services or selling items. It is important to remember that there is no way you can get money for free so beware of scams.
