Hey those are preety basic ways to earn cryptos, you could join bounty campaigns here or participate in airdrops but do your research as many of these coins go bust in long term. Another way to earn is to sell services, and accept cryptos as payments if you don't have any services then you could become a reseller and sell here. Lastly you could lend cryptos, and earn interest over it but make sure you do your due diligence before you lend your coins.
