Well i don't know how much you have learnt already but to claim the bitcoin gold you will need some bitcoin when the fork takes place. If you have bitcoin i would recommend downloading exodus or electrum wallet and moving it from the exchange to your new wallet. As for other airdrops there are not many that are worth much right but there is a site airdropalert that may help you get them all. Just google it and find your way from there. I would probably join some crypto facebook pages too to help you learn more about the different coins.
