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
Many people are making good profits by trading altcoins but that is possible only if you have good knowledge about the market and if you hold a good experience of trading as there are many people who invest blindly without collecting any information and end up loosing everything but if you have good skills and knowledge then investing in altcoins is the best thing to do.
