Many coins and tokens have a Telegram group. Telegram is an instant messaging and group chat application (similar to WhatsApp or Signal) which is available for Windows, macOS, Linux, Apple and Android. It is useful to visit the Telegram group of coins / tokens you want to invest in as that is normally where you can find information on the most recent developments and status of the project. It also gives you a chance to ask any questions to the team and community.
You can download Telegram from their website here.
