I was in a similar situation and had to do the same i.e. un stake my synthetic (-1 - transaction fees (TF)) and close my stab pool, close my CDP (-2% -TF), and reopen it + new stab pool with my new wallet (+1+5+ TF)…
I did not see any other way, even if it came with substantial fees, as the position had not been created for a while…
I switched to another pool for extra rewards and a few days later got a NFT from that pool to claim the additional rewards. That NFT linked to an identical site of the delegation pool and it drained my wallet… I made a new wallet and transferred everything to this wallet.
But I’m now paranoid as hell, I don’t dare to sign anything anymore, I don’t dare to click any links even from moderators or people who claim to working for Indy or any other project. Also people who approach me via discord channels are getting a block. Also don’t want to try anything fancy anymore like staking with new protocols as they could be scam as well.
I don’t think those scams are linked to price action of the iAssets.
