I am very interested to know how you make money from here with testnet. I am only working here on signature campaign and I can't earn from anywhere else. If I can earn some money like you said it will be my biggest support. I want to know whether testnet work is very easy? Is there any medium to follow to learn them? Please let me know. I know from your details that you have earned a lot of money from here. Many people talk about airdrop campaign but there i joined and worked but till now i didn't get any money.
Brother if you really want to earn from airdrops than you have to learn that not every project will give you descent airdrop. You have to check project first and then do all possibly task to qualify for early supporters airdrop. Currently big projects where airdrop possibility is high are Zksync, Starknet, Layerzero,Scroll, Linea and Base network. You are Bangladeshi person and there are lot of Bangali channel on Youtube where you can learn airdrops(Testnet, Retroactive). I will recommend this channel.
https://youtube.com/@CryptoEnglishARB supply is high. ARB won't reach higher prices with much more supply, but ARB could go from $2 to $3 if Bitcoin reaches $100,000. From here I can say if you invest in bitcoin or ethereum you will get more success with less risk.
Arb is strong project and we can guess the potential of this project from their daily transaction and project launched on Arbitrum project. People are staking Arb token in large amount which is good sign for token price. I think it will easily jump over 2$ when btc stable above 50k$
