For the first link there's a scam suspicion because:
1. Literally no reviews or feedback online
2. The web-site created around June, but web-site states that first user posted around May
For the first link there's are arguments it might not be a scam because:
1. It's invitation only web-site and invitations are sold on darknet
2. On the invitation seller on the darknet there are positive feedbacks of at least 20-40 purchasers
For the second link there's a scam suspicion because:
1. There are also no reviews of the service from investor side
For the second link there's are arguments it might not be a scam because:
1. The mixer is wellknown and there are a lot of reviews from consumer side
But ultimately its not very clear about both of them, so looking if anyone here used any of them.
