That is correct. On the StadiumArcadium webpage, Lithium holders were able to swap their Lithium for MyFriends and Arcadium tokens. Over 97% of the tokens were swapped out. Additionally, the founder gave refunds tot many of those who missed the swap due to language barriers etc. Now, prior Lithium holders are able to pre-stake our swapped MyFriends and Arcadium tokens.

The dump was due to liquidity being removed from the Lithium pool as the token had no more use case. It was all very clearly communicated to Lithium holders/investors. Nobody got rugged. The Lithium token is now a meme and can still be traded, but it is not supported by the project (because it has moved to Layer 2).

If you go on rugdoc.io you will see that StadiumArcadium is deemed low risk. This is one of the most impressive projects in DeFi that I have witnessed so far and is being handled professionally. With that said, there is always risk in Yield Farming and in Crypto so I am only sharing my observations. This isn’t financial advice.
