title: What's Telegram chat memory space limit?
body: <p>The Telegram has a cloud storage for users self-chat. Limit for uploading files - 1.5GB, yeah, I know about it. But I didn't find something about space limit for a chat. Is it unlimited? I mean, if yes, I can create Telegram-bot for cloud storage? Just, I have more than 20TB files and can I use Telegram for my site files storage and don't be afraid for safety/keeping?</p>
