Everybody have a lot of addresses for multiple crypto currencies on wallets, exchanges etc
It's annoying because you must open the wallet/website everytime and you can get confused if you do it frequently.
To fix that, there is Hodle.me which allow you to store or share your addresses online and get access to it in one click.

Interesting idea and this could work when you are an individual or a company that needs to receive donations. Without the need to have a list of many coins you provide simple link. However trust in the provider that our addresses won't get changed might raise some concerns tho
