It just keeps erroring out when trying to claim reward or just sits there hanging for ages.

I gave Atomic Wallet a try. I assume that not a “exchange wallet address?” Others have said they could not claim either for whatever wallet they were using.

I also don’t belive it’s $25 worth of Zil. It’s 25 ZIl so like 17 cents there “campaign” says max of $3,500 worth of Zil for the pool.
