I think you should join the market because it will teach you skills such as managing greed and fear.
I think to be a merchant it's better to join the community in bitcointalk, because that's where there's going to be some who want to teach you how to trade good and good. because to be a trader is not easy and the risk is also quite large later
Based from my experience, it is easy to become a trader but becoming a good trader is not. It takes a lot of patience and understanding of the market, and dealing with personal emotions when you are going to trade or if there is a current dump is the worst part. I was once a newbie trader and have also mistakenly participated with the dump. It was not my intention to sell if it is not for financial needs. Bitcoin was about $1 800 back then and it always come to my mind that, "what if I didn't need money that time?". I could have gain a very big profit from that. Anyways, as much as I want to regret that move I can't because it already happened. The money was used for a good purpose anyway.
