A Beginner’s Guide To Micro-investing

“Micro-Investing” describes small amounts of money being deposited, saved, and invested into an investment account. Micro-investment platforms aim to eliminate barriers to traditional investing. To remove the obstacles to conventional investing, trading fees and minimum account balance requirements are generally removed from micro-investing apps.

Traditional investingcan be scary for people who are new investors. With Micro-investing, there is no such fear, and investing can become easier and more accessible.

What Are Micro-investing Apps and How They Work?

Micro investing apps allow users to invest small amounts of money. The app usually makes saving easy. You can quickly round up your purchases to the nearest dollar or set up automatic transfers using a micro-investing app when you connect a debit card. 

The simple way to put it is to invest with a small amount of money rather than a large amount. You do not need large money to start micro-investing; you can start as little as $1.

If you know nothing about stocks, you can still invest small amounts of money using micro-investing apps. They manage your extra cash by creating customized portfolios of stocks.

There are 5 different portfolios that investors can pick from based on timeframe and financial objectives. The portfolios can be traditional or even aggressive.
