1. Is Sweepstakes illegal in the US?
It's illegal in some states. You can read more on onlysweeps website

2. Is Sweepstakes gambling or not?
If you buy gold coins for your own money, then yes. If you just ues the AMOE methods to play for free, then I wouldn't really call it gambling. Possibly bait to gambling.

Stake is easily my favorite of those. I'm a platinum 4 vip and i keep getting nice reloads pretty much every day. Not sure if you can find the breakdown on their site but here is the best stake.com review I found that explains how their VIP process is structured.

Description: Crypto news site with brandable name. Verified on google news.
Starting bid: 1.5 BTC
Buy it now: 5 BTC
End date and time: 2018-03-30
Payment methods accepted: BTC, ETH, LTC
Additional information: The site has over 100 posts. Twitter and fb accounts included in the price. The website is not making any revenue yet, just traffic. It got approved to google news yesterday. Selling because I have no time to continue with the project. Big profits can be made by selling ad spaces, promoting products and whatnot.
