The merchants will also be happy with this project if it happens as they will be able to adopt any coin they want for their business and they will be able to send the coins on the project with only one username. They will not need to keep multiple addresses for sending and receiving money from their clients.
It is a brilliant point which you discussed at this place, it will really be a great support to the merchants as there are many coins and people use multiple coins and for that it is very hard to take the support for all the coins at a time so with this app the merchants will have only one app of Tip Blockchain and they will use all of the supported coins with one username.
