I prefer to join the bounty campaigns that have no such silly requirements. Downloading third-party applications is not safe for crypto investors, the malware can clean the whole hardware, private keys less than a minute. Specific requirements should be tested and checked carefully before downloading anything.
Most of the times, I see malicious links sent to telegram groups and they have their ways in which they lure people with their enticing words.
Also, most projects that demand that apps should be downloaded, do not last long and do not end up well as thought, except for few ones, so why then should one download them.
Malicious links are hidden by the programming skills, every telegram should open carefully the sent links in order to protect the personal computer from the virus, spyware, trojan. App downloading and giving the public address of coins that have its blockchain is a good idea for increasing the downloaded statistics on play store and Apple store.
