0.10% APY Kraken Opt-in rewards for Bitcoin

I noticed Kraken’s "Opt-in Rewards" program for BTC at 0.10%APY (instant unbound, 0.15% for 30 days lock) .

Given the history of "earn" programs on other exchanges, do you trust Kraken enough to leave BTC sitting there for this low API? I have about 80% of my BTC in cold, and they will never leave except for other life investement but I am wondering if it is worth the risk to gain this little bonus.
