Blockchain tipping
Idea: Allow for an easy way to send donations in online world - sending small tips to artists, journalists or some random guys that are always helpful on forums.
Functioning: All it does is simply showing an address that the donation can be sent to. In the case of Bitcoin it can be done through QR code, in Ethereum one button is enough that will generate a transaction in Metamask to be sent on specific address.
Advantages: There is no need for any registration for both sending and receiving donations. Donation is sent in seconds and in couple clicks.
Disadvantages: There could be a way for a hacker to replace the address for his own, essentially redirecting the money to himself.
