One airdrop has been asking me to cash out the tokens using my TON wallet, but when I try to, the prompt I receive is that I do not have TON to complete the transaction. Must I have TON to receive Telegram-based airdrops?
It's just like other blockchain networks like ETH, BSC, and ARB, where you need to have a balance for each network for the gas fee. It's up to you if you want to transfer Ton to your balance, and you'll really need it so you can make a transaction using the Ton network. That's how easy it is to understand.
So do you still believe that you will receive big rewards from the airdrops on Telegram? It seems that I have seen a lot of people who did not fulfill their promises in the distribution of their airdrops.
It would be better to have lots of projects like that to get at least one allocation that would fulfill them. It's hard nowadays, but it's possible. People can be mad because they don't see the big numbers that they wanted to, but, it's still money and possibilities that come basically out of your sweat (if there weren't activities like swaps, bridges, etc.), so all the profits are appreciated, in my opinion.
