I don't know anything about that website you have shared, neither do i intend to waste my time to check it out.
However, i think it is important you understand that almost all cloud mining offers is a scam and if you get into it, you are surely going to lose your money. The scammers often promise you guaranteed returns, plus they claim that they are anonymous, etc. There are other red flags to look out for, but just to be safe, forget about cloud mining.
The domain itself is well-known that site offers Braiins OS for ASIC units the only problem is never heard that they have this sub domains.
By checking the site, it looks like renting a hash rate, but why did it say, "Try your luck"? It's weird; it looks like you are going to rent but the profitability depends on if you are lucky to hit and mine a block. Or maybe it offers solo mining, and if you're lucky, you could earn the whole block reward.
I check the minimum; it looks like around 0.5 BTC, something that is too expensive.
Take note Braiins.com usually in a Bitcoin mining section. If any of you have doubts, check the mining section.
