As we now know that Grin and mimble-wimble is not really private as people was thinking,
I am not really sure how long will Grin be supported in bitcointalk.

No one says that Grin is really the most anonymous coin but it really offers good privacy protection.
Theymos talks himself about Grin's privacy:

Monero = CT + stealth addresses + ring signatures. Grin = CT + "stealth addresses" + mimblewimble. Because grin replaces ring signatures with mimblewimble, its privacy is less reliable than Monero's. Probably the grin developers have tried to make their mimblewimble transaction aggregation methods good, but I currently wouldn't put much faith in it, and IMO it'll take many years of research to get something really solid. That said, CT + stealth addresses offer a certain base level of privacy, and grin's method of handling stealth addresses (using an interactive protocol, exchanging "slates") is both more scalable than Monero and probably more private.

If your goal is to mix coins, grin is definitely not for you right now, and it may never be. Monero's goal is maximal privacy, regardless of the cost. Grin's goal is excellent privacy, consistent with scaling.
