Daimakerdao?
Are you aware that there is an existing project known as MakerDAO and they have a stablecoin known as DAI in late 2017?
Their official site is
https://makerdao.com/en/The choice of the domain name clearly shows that the scammers are trying to trick people into believing that it is the site behind the MakerDAO project.
i am more on this idea. scammers using popular crypto projects trying to connect their name. but for those users who will not do their homework, they will think that they may be related to them.
i can agree with the suggestion of rikafip here, better buy your satoshis and store in your own wallet. in that case, you are very sure you have your satoshis. but with most of these mining sites, they will just siphon your funds and promise high rois or anything that they can attract the interest of naive users.
