Sometimes I feel a day will come when we may need to encrypt ourselves to prevent our life. The days were not too past when a man could have handled his whole belongings to other in the name of trust.
Now everything has a fake alternative even the tokens. Blockchain has reduced burden of centralized institutions but who will fight for fake alternatives.
You did a good job to aware some people about the threat of fake coupons. We need in life people like you and not the fake currency creators who can make hell of others like with their, criminal genius mind.
Regards.
