Platforms
There are a wide range of platforms that offer cryptocurrency rewards for watching ads and completing other tasks. These services are often not part of the cryptocurrency community, but actively use cryptocurrency to attract new audiences and reward their regular users.
Here are some examples:
Brave Creators

It is a rewards platform that allows content creators to earn tips (in BAT cryptocurrency) from their subscribers and readers.
This platform allows you to monetize the content you create on the platform and receive cryptocurrency for it. Brave Creators works on the basis of Basic Attention Token (BAT). Accordingly, all donations are immediately converted into cryptocurrency.
There is no guarantee that people will support you with tokens, but if you love and know how to create interesting content, the reward will not take long to come.
Brave Rewards

This is also a service from the Brave platform, but aimed specifically at issuing rewards for completing tasks and promoting the platform. Here you watch ads, for which you receive tokens.
Tokens can be withdrawn immediately or, for example, directed to support the authors of Brave Creators. So both services of the platform complement each other, and you, in turn, can try yourself both as an author and as an active user.
Bituro

A mobile application for completing tasks in exchange for bitcoins and other cryptocurrencies. Available both in the App Store and in Google Play. In addition to completing tasks, you can also take surveys and receive a bonus for each one. In addition, the platform has its own referral program, meaning you can invite your friends and receive cryptocurrency for their registration and use of the service.
Also, the platform holds a special lottery once a day, where you get a significant reward for winning. You can try your luck. Participation is free.
By default, the points you receive inside the app are converted into dollars, but you can convert points into cryptocurrency by specifying a Bitcoin or Ethereum wallet
JumpTask

Another multifunctional platform with an internal token that is easily converted.
The tasks are the same: viewing ads, solving captcha, writing posts and playing games. The surveys that the platform presents are quite interesting and are easy and quick to complete.
To start earning in this service, just log in to your Google account through the platform. No additional multi-level checks. Only pure profit.
