Do you know that most traders and forum users here lies about their dealing in bitcoins. Some exaggerate to their family and friends the unrealistic profit they claim they are making online through bitcoins and these same liers don't tell their losses. Have you ever lied or bragg to your friends about bitcoins.
Unfortunately, but on this forum is many scammers who only call themselves traders. They are looking for 'Newbies' on Bitcointalk and promising them easy earnings to extort money for a non-existent investment. Pump&dump groups are also 90% simply scam. The main thing to remember is that no one will ever give anyone money for free, there is always a risk. Don't trust in shady proposition, always trade only with trusted members or with escrow.
When it comes to trade itself, it depends on the trader himself, whether he likes to talk only about successes or about losses to. In my opinion, this is a private matter for every person. You can evaluate him and name him as you like.
