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.
Yes higher capital will give you higher profits but even the risk would be higher but that can be managed if you are really looking to make good profits in short term and that is possible with altcoin trading so before investing do a good homework and choose the right coin at a right time for making an investment.
