How safe is it to indicate the details of payment systems for fundraising?

Question

Payment systems

I am making a small program, I plan to put a small note about the support of the author in the "About" window, indicating WebMoney wallets (WMZ, WMR, WMU), Yandex Money and Bitcoin.
Just in case, I want to clarify - how safe is it to publish such information? My accounts are actively used. And if everything is more or less clear with Bitcoin (you can simply generate another address for a specific purpose), then with the rest it is not entirely clear.
PS: In passing, another question arose - can transfers be made to previously generated Bitcoin addresses? Those. are they valid? As far as I remember they should work, but I want to clarify.

Answer 1

About the program:
Many people do this. You don't give out passwords. This is equivalent to posting the address of your residence on the fence near the subway. Naturally, this will be made public, but if you yourself add on the fence: "I'm out of the house from 8 to 17, the key is under the rug by the door, the money is in the closet," then this already slightly changes the degree of security. Although the majority, as always, will not care.
Now there are no problems with the creation of add. details. The same wallets can be made as much as you like, there are also virtual bank cards, there are also various other ways to hide your real data.
But seriously, there are no problems in this. It's more of a fantasy thing.
After all, you can add a link to the page where it is possible to make a donation in the information about the program. Or a link directly to the payment system, in which, by default, initially you do not "shine" any data. (payeer)
- Yes, they are.
