If You’ve Been Scammed Out of Cryptocurrency It’s Probably Your Fault
Scammers are a dastardly, low down bunch. Preying on the gullible, extorting the vulnerable, and hoodwinking the hoodwinkable with their promise of free bitcoin if you send a little first and daily interest on your Bitconnect loan. It’s an indisputable fact that if the cryptocurrency space were cleansed of scammers, the web would be a better place.

With regard to maslaha, the world's unbanked number in the billions and represent the majority of the world's adults.”

What is more Bitcoin may be more Halal than modern fiat money. Matthew (Blossom Finance, a fintech startup based in Indonesia.) puts it quite clearly as he remarks, “Bitcoin is more halal than any currency in wide circulation today but probably still falls short of the strict and narrow definition of money in Islam. Modern sovereign currencies are based on debt with usury - this is strictly prohibited in Islam. Therefore, all modern money is not halal. Bitcoin, on the other hand, is not based on debt - it's based on a proof of work - and this is at least not haram (impermissible).”
