I think that if you don't want to risk a lot. the best thing you can do is buy coins at a good price and do hodl, for example, everyone knows that there are coins that will go up in price as ETH, that's why you buy it when it's worth $250 and sell it in December when it's probably worth $500, you can also try to trade, buying bitcoin and some alts that fluctuate a lot in a week, you can try to generate profit if you predict the market well.
