<prompt> Human: Im in school and a buddy of mine whos 27 so may have significantly more money than me. I dont know if thats pertinent or not so Im mentioning it told me about this app Robin Hood and I thought Id come here to ask if any of you had experience with it.Also I only have about 1200 to my name not all of which I can invest with due to rent and car payments and tuition and my dad has discouraged me from investing saying its not worth it for me to invest in such small amounts.So my questions are:1 Is the Robin Hood App effective?2 Should I wait to invest when I am more financially stable?3 If I do invest now with 50-150 at a time, how quickly would I see a turn around or profit?If you dont have answers to all three, feel free to answer just one or two. Thanks in advance.  <response>: I think your father is correct. Youre young and you need to save some money just for regular expenses and education.
