You've based it on Bitcoin technology. Is this a competitor to Bitcoin?

Absolutely not! The two serve quite different purposes. The properties of Bitcoin make it analogous to precious commodities like gold or silver, and it will always function as a useful store of value. Freicoin, on the other hand, is meant to be used as a medium of exchange only, kept on hand just long enough to provide a cash-flow buffer. The demurrage fee encourages recipients of Freicoin to put their money to use as soon as possible in an exchange (even by buying bitcoins, for example), whereas the deflationary nature of Bitcoin rewards hoarding and serves a different purpose as a long-term store of value.
