After a couple of unsuccessful attempts to find something clear on the topic of P2P trading, I came across one compilation. It covers all topics at once - from basic principles to nuances of security and investment approaches. If you are interested in more details, you can go to the link and quickly get into everything important.
I'm still only interested in the topic, but I'm scared about security - I don't quite understand how to protect myself from scammers in such transactions. Is there anything sensible about that in this compilation?
