Hi, we have created an application in which cryptocurrency can be sent by phone number, even if the user is not registered in the application itself! What do you think, how much will this mutual settlement between users simplify?
I would prefer to say: Exposing phone number to any apps is never a good idea. Phone number can be used to do KYC on many platforms, and the more exposure you do with your phone number, the higher risk your phone number will be abused. It is a kind of risk management. I don't trust any third party apps that require my phone number to operate any transactions. That's very risky.
The risk is present on the way to the kitchen)
In our world, you do not need to relax and keep yourself in awareness and control your external transitions ! And as for specifying the phone number or not, so the phone number has now become a mandatory factor wherever you go, with whom you would not contact, even in a restaurant booking a table, they ask for your phone number, so there is only control and be careful! And if you talk about the risks and what is better and safer, I do not know this on earth, even in a children's sandbox there is a risk of being blind!
