Be cautious about tokens or services promoted with generous free offers that later require payment in a specific new token. Research the project, its team, and token utility before purchasing or committing funds.
Just ran my first free QoRTrace scan, amazing. Just for this piece, incredible output and visuals. Explorer based, PDF download, on screen visuals, additional text detail. For a free scan! I would reduce that 50 free down to 10, after that, pay in Krown tokens. 😀
