Yes it also depends on how long your friendship is, also if they also trusted you.. i have deal with an online friend like that before. He made me the middleman of a transaction and basically i got his money ofcourse i didn't do anything and give to him after. But he trusted me so when he ask me a favour i couldn't say no.It depend on who am dealing with, the level of relationship that exist between us and the number of years we have been friends enough to trust him or her with such a large amount of investment to avoid being duped or defrauded.
