I believe that the lack of development is the main factor for the decline of this currency, including advertising, despite the advantages it has. After the forum administrators decided to add the Grin payment feature to purchase Cooper membership, I was surprised after years that the number of those who registered using that feature was very small.

The success of Grin depends on two factors:
- Launching new features: If Grin team can add new features that attract users, it may be able to reverse the current trend.
- Increased interest in privacy: If interest in privacy increases in the world of cryptocurrencies, this could also be beneficial for Grin.
