I made about $1500 from selling eBTC, ETHD and some small fry, but I haven't for a moment considered investing a cent in any of them. Most of these airdrops are such blatant cash grabs it's making me ashamed for this dark corner of crypto, but FOMO is a powerful emotion and even a thin veil of legitimacy can cause quite the pump. If you don't understand why a certain project offers a possible solution to a problem that is best solved by means of the blockchain, don't invest in it: a fool and his money are soon parted.
