I'm wondering if this coin still has a future, especially when privacy on crypto has been frowned upon by mainstream governments. Do you think it can be good long-term investment like Monero? Or is it a complete bust? Your input would be greatly appreciated. Thank you very much. 
If you look at how successful Grin was in the past and also his current condition, it's quite sad. Actually, the project is still ongoing and I see that their community is still active. However, to return to the conditions at that time, especially to reach the ATH again, it really requires a very wild effort and it may not even be easy to happen.
