Stash is a mobile application that is made for the long term investor. This app was created just to make you money. If you know very little about investing but want to make money doing it. Check out some of the Facebook groups and reddit boards dedicated to Stash. They usually have tons of articles and have very helpful people to explain any questions you might have. Plus, from time to time someone might come up with a stock you where not thinking of. Of course as always results are not guarenteed. Invest wisely do your research before making any investment.
On a personal note I have been using this app for two years and have an interest rate a crossed all my stocks of 120%. There is no bank in the world going to give you an interest rate that high. Do your research take your time. Make smart decisions, invest in things you know and let your money work for you over time. These companies do not generate revenue over night and neither will you. Give them time and they will make your a very happy Stasher.
