Why Cannot I Receive Tips&Airdrops

Possible reasons are as follows:

Your Telegram-linked Cwallet account has been restricted to trade and receive cryptocurrency.
The airdrop command in the original tweet is invalid.

Causes behind an invalid command:

1. Insufficient balance

2. Wrong command

3. Tokens of the airdrop not supported in Cwallet

4. The user who sends tip/airdrop is restricted to make a transaction (send cryptocurrency).
