Not sure about you guys, but the domain name itself sounds too shady to start with in my opinion.
Pretty common domain for scammers to use. If you see domains like; btcprofitsdirect, btctraderpro, btcwalletsafe, etc it's 99% likely to be a scam.
http://whois.domaintools.com/btcbuyerseller.comDomain is registered like 6 months ago and only for a year, of which 6 months are left, which isn't a good sign either. Serious businesses register their domain for at least a couple of years, and they will pick a short and brandable domain that looks professional.
