Dont join to air drop using your mew or just in case make another mew for airdrops because airdrop token mostly are scam now and hackers are there always. And dont click suspicious website also sometimes those are phising site . And dont use your mew into computer shops too many hacker there too they might use your account if you done erase the link or cache when you leave the shop so, make sure you erase all the possible that can trace your account.
