If you're referring to this site btcbuffet.com, I don't know if they have any representative or support here, why don't you try to contact them via their contact page? They're the only one who can help you anyway. And seriously its cloud mining/ponzi site lmao. If you can't login probably there's a high chance that they are running now.
Their contact page also has a captcha that isn't working. Contacting their support is ironically impossible.
I already tried to contact them. But there is the same problem with the captcha. I only know, that it is a very young provider. Maybe they have to fight with technical issues. I will try to login again later. I asked here, because I found no news on google search. But thank you for your fast reply.
I think it is more plausible that they simply exit scammed their "investors" as it is obviously a ponzi scheme.
The site looks like a copy of
https://adbtc.com, but they added a nice MLM flavour to it, essentially making it a ponzi scheme. A lot of google search results that turn up when googling this domain call it "legit", but i sincerely doubt that when you have a catchphrase of "The Magic will happen" and no explanation where you pay the refferal earnings from.
If i may ask, how much did you invest into this site?
