If you got 10 USD in CUB and 1 LEO is for 0.1 USD when snapshot happend, you will get 100 LEO. Simple as that.

Yes. Initially, I thought it was 1 CUB to 1 LEO until I read the post.

I do not know when they do the snapshot, but 0.115 USD per 1 LEO seems to me a lot - maybe they do the snapshot on purpose when the price was the highest? Because $0.115 per LEO was about 1 day or so. Since then, it has always been below 0.1 USD.
