Telegram crypto AIRDROP bot

We're looking to develop a Telegram bot to create a referral campaign for a Telegram group. The goal of this bot would allow anyone interested to invite friends in a Telegram group to get a unique referral for such. The bot would keep track of which users join under each participant and also provide a function for updating the participant's crypto address for them to receive rewards.

The first thing the bot should do when started would be to send a customized message.

The bot would have to have 4 functions.

GROUP: Prompt users to join the Telegram group.
LINK: Provide a referral link
ADDRESS: Allow users to update their ETH address and store this info for future queries.
STATS: Show stats for each referral.



Information with each user's address, telegram username, and users that have been referred under him should be stored.

Example for such bot:

Optional bonus: If you can integrate the bot to keep track of results in a readable google spreadsheet.
