Telegram Shop Bot for Data Sales

I'm looking for a skilled developer to create a Telegram shop bot that can sell data through text files and spreadsheet rows. The bot must operate outside of Telegram and has to enable users to load their balances with various cryptocurrencies.

Key requirements:
- The bot should sell both text files and spreadsheet rows.
- It must support all major cryptocurrencies for balance loading.
- The bot's interaction interface is currently undecided, so a flexible developer capable of creating a web interface, mobile app, or desktop application would be ideal.

Skills and experience:
- Proficient in bot development, particularly for Telegram.
- Strong understanding of cryptocurrency transactions.
- Experience in creating user-friendly interfaces, whether web-based, mobile or desktop.
- Ability to sell data through text files and spreadsheet rows.
