It depends on why you want side income in the first place. Is it your long-term investment plan, your retirement preparation, or you simply want to make “quick money”. Each of these has different avenues.
Let’s start with your immediate need. If you want to have a side income source that makes you big money quickly, cryptocurrencies is your go-to. Bitcoin, Ripple and Ethereum are your best options right now. Each of their values is expected to increase manifold in the coming months and year. They are your ideal short-term investment plan. (Their long-term looks quite uncertain!)
For your long-term income plan, stock market is probably the best option available to you. It’s not only safe, but if you manage to craft the right strategy, your money in shares can provide you big and consistent returns. To that, investing in stock market is fairly easy, with countless resources available online.
For your retirement plan, there’s a range of things you can do. You can first apply to government benefits and apply for right LIC.
All these ways are fool-proof, guaranteeing good rewards.
