First of all I have no experience in investing. I have 0 assets and am in debt, so I don't have anything to invest. But I do notice a market aspect to this, and I'm curious. If I want to invest $20-$100 here, watch it grow and sell to get a higher return when the time is right, how do I go about doing that? I have tried going to https://steemit.com/market.html I fill out some numbers in the buy section, I don't know what specifically each line means, but no matter what I put in those, I get " Transaction broadcast error. " I don't understand this. Do I even have the right idea in the first place, is this the kind of thing I can put money into. Can I use my credit card? How does this work? Any specific instructions are appreciated. Thank you
