It means any business offer or opportunity carries risk.
I trade FX for myself, been doing it for 4 years, still a nob.
All I have learnt so far is that anything carries risk, the risk of you losing your profits, plus your initial investment.
I have no one to blame for my failures, I did burn a few thousand EURO in the "learning" process.
And the advice is, only use money you can afford to lose - it also means that, indeed, programs, opportunities and businesses exist that can do the trading for you. But trading by it self involves a lot of risk, so don't expect the holy grail on whatever is advertised. Give the others an opportunity of doing it for you, but if you expect to become millionaire overnight... and just in case something goes south, don't throw all your life savings, just what you "don't need".
Regarding BT, so far, they are doing what it says on the tin.
What is amazing is how this thread is so biased regarding BT, I mean, bad mouthing.
You can't find the same amount of pages (or advice

) regarding well know scams and HYIPs.
There's only "warning" after "warning" in this thread - we are now on 20 pages of "scam, scam, scam".
Kind of strange, don't you think?
