It is close to 2 months that i have leased out but dont see any update on if i will be getting a return or not.
I am leasing my few WAVES for more than half a year now. I'm on the 3rd site now.
One place was paying of my earnings the tx fee and since my WAVES aren't many, I ended up with less than 50% rewards.
The second was good, was sending 1-2 times/week, was paying the fee from other funds, all great. Just they are closing and don't send rewards for some time now.
The third uses different funds for tx and send daily. It's a bit of overkill, but I'm OK with that.
All in all, it depends on how much waves you have, some sites don't send anything if you have too few or gathering your rewards until a minimum amount is reached. Or, as I said, some are dead (or just not paying ?).
You have to read more, you have to get to a list like this one and find one that suits you best.
Edit: I use now http://www.pospool.io/
Edit2: TL;DR; If you got nothing in 2 months you better switch. Go here open each site and read more, maybe you find a good choice for yourself.
