Not all Airdrop are scam, some are legit and will definitely pay hunters, some will pay but will later worth shit while some will pay something reasonable. What hunters need to do is source for a legit Airdrop to do and not just jumping on all Airdrop link. Airdrop is still paying.
Both are good to invest in but I prefer Eth to Bnb because ethereum is second to Bitcoin with a very stable price. Ethereum network has alot to offer, with this i sensed Eth will be a good coin to hold for a very long time.
Is true bounty hardly pay this days, and the few that has paid so far paid with a very shitty reward which makes hunters started looking for a way out, buying ICO for me is a No, but I still believe trading altcoins is still profitable.
You can't compare Binance IEO program to that of Latoken, check records of project that has conducted IEO in Latoken, many of them turned out to be scam project and some failed due to not raising required fund. So kindly read more about the project before investing.
