I've been trading since 2007 so expect a quick and smooth transaction.
For clarification, you have not been trading bitcoin since 2007. Bitcoin was created in 2009 and only started trading in mid 2010.
It is obviously advisable to use a trusted escrow when dealing with this person, and you should not send first because "paypal is reversible"
Correct, I've been trading in other digital items since 2007. Thank You,
You'll get much more interest if you post some references. Anyone can claim they have been trading since 2007
For the 1 Year+ on BitcoinTalk part, most will just assume you've bought that account. Last post on February 02, 2014 and next one was seen this month on April 18, 2015.
Just trying to help you out. Right now most are just gonna assume you're one of those people with a bought aged account buying with paypal intending on charging back later on. That's just how it works around here.
