As with many other cryptos, you can stake your DOT and earn rewards. Staking is where you lock your DOT tokens up for a period of time in order to earn interest. This interest accumulates as DOT, which gets added to your initial balance. For faster growth, look for staking opportunities that offer APY and flexible staking options. That way, you can benefit from the marvel of compound growth, and if it seems like the markets are going to crash, you can withdraw your DOT and convert it into a stablecoin until things settle down.
