So far i dont see any investment with high return and have a less risk.
If u only have 0.1 in ur wallet go to trading altcoins, but u need knowledge about the coin and u must choose when to buy and sell ur altcoin. Good luck sir
It's better to trade with alt coins with that amount and you can buy bulk of alt coins that you can have good profit one day. Just take the risk, whether it is high or not but remember that the capital you are going to invest will have equal effect for the profit, if you invest low, you'll get low. Don't expect it will be higher.
