My experience with launchpool is bad.
I staked $5,000 for 5 days, I only get $10 worth of other coins.
Then the second time, I staked $5,000 for 4 days, I only get $0.5 worth of other coins.

I joined when launchpool is already widely known, probably the 4-5 months ago. Before that, it looks like launchpool was quite promising, but now it's no longer a good rewarding.
