#Solana airdrop on web3

Two days before airdrop participated, after airdrop unable to transfer the tokens back to binance exchange and also swapping features not completed. For transfer it shows block hash not found. I recently created this Web3 wallet under binance offer. Contacted binance support bot. My initial experience with web3 not satisfactory. Please share your opinion on how to proceed further inorder to secure my tokens and wallet.
