This website crypto-shex.net is run by an individual named sukanta bhowmick who also owns www.cryptocoinshopping.com . This guy is a scammer who has run off with around 10 crores INR to dubai and is not returning the money. I also lost 0.24 btc on this website.
Please do not invest any money on both of these sites. Me and many others like me have been scammed by this guy who promised high returns on investments on his website. Initially, everything ran fine for 2-3 months but since November, he is not paying any money to people.
His typical schemes were : Get 15% returns on your investment.
For example, if you invest money in 1 btc, u will receive 1.15 btc in 37 days.
When price of a BTC was around $2000, people invested a lot and since then, the price of cryptocurrencies have skyrocketed, this guy has not returned money to the investors and ran off to dubai.
Please do not invest any money here. www.cryptocoinshopping.com or on www.crypto-shex.net
