Thank you very much bro you have guided me with your valuable time. I joined the channel you provided and watched many videos about airdrop and testnet. I will practice all the knowledge from here but I request you if I don't understand anything anywhere I will follow you please help me that's my request.
Don't worry dear, you can reach me anytime. You can ask me in personal message or DM me on telegram (@Gladitorcomeback1) will check and reply im free time. Remember that all testnet are free and you need only testnet token which are absolutely free and you don't need to pay for it. In retroactive airdrops you have to spend some fund in bridging, swapping purpose to complete all task. Don't rely on just this Youtube channel and always research about project before joining any compaign.
