Blindtalk is a messaging platform where senders post messages in the open and expect the receivers to search for them. While the senders are anonymous, the receivers are totally unknown to the platform.
How to make money? Post a message. You need to hold 1000 Blindtalk tokens before you can post a message. You only need to pay 1 Blindtalk token per post. You buy 1001 Blindtalk tokens at a low price. Make a post. Then you sell back 1000 Blindtalk tokens at a high price.
The more messages people post the more Blindtalk tokens are bought. Thus, the price of Blindtalk tokens will go up. And the longer the Blindtalk tokens are being held the stronger the price will be.
How to respond to the messages? Every message comes with its sender crypto-address. Send a token to the address while attaching your response in the description. Or, you can just post your response in Blindtalk and let the sender search for it.
