Why do you think they are bitseven under a different brand? similar interface? cause that's a pretty weak basis. Lots of scam websites copied cex.io and binance and there was no stopping them from it. If bitseven really had a good reputation, it doesn't make sense to go under a different name (hiding that they are bitseven) and start building reputation from zero all over again...
I agree with the members above, the way OP struggles to take in red flags and just continue to shower compliments, definitely makes this look like another attempt to subtly shill...
