hey everyone I would like to introduce myself to the forum.. I didn't find any introductory sub forums so I figured I would put it in the beginner section as I think it's most appropriate!

I wanted to know i can somehow invest these coins into a company to in turn bring me a higher amount in the future? how does selling and buying work on localbtc? i see that the price is around $310 as of this post but some vendors are charging upwards of 340+ why is it more expensive? well hopefully there are options for me out there on what i could use them than just letting them sit there.. hoping to reading suggestions from this forum! Thanks! 

so I did the class but the person didn't break down the steps of how to use the thing so pretty much I ended up buying a couple of BTC's that were supposed to be used for the bot but since I have no experience with the program im kind of stuck here sitting on the coins... so my question to anyone who can help is.. What can I used these coins for? I don't want to exchange the for USD because im pretty nervous about those localbtc.com vendors and meeting 1on1 to swap it..
