Does the Wallet Promote Address Reuse?
I really don't understand what you mean solely based off of the title and this post, as the English is kind of broken and unclear, but desktop wallets typically don't
encourage address re-use, they simply allow for you to opt to reuse an address, or simply not use it again and use another. For online wallets, they more often than not do not promote address reuse and a majority of them will generate new addresses every time you wish to receive some Bitcoin. As for exchanges, typically they generate one address for you and then you use that.
