If you use Moneybookers then a very simple way of doing this is to just add a new email address to your Moneybookers profile and use that email address to deposit/withdraw from the new trading Betfair account.
Again though, please don't create a new betfair account until we've had a chance to organize the promotion, a requirement of participation will most likely be to open a Betfair account via the TGT affiliate link which will go towards funding the prize pots involved.
Don't worry wndllll, you *shouldn't* lose it all in one go.
Always have an amount you are comfortable with losing per trade. If you are scalping, that might be just 3-4 ticks you can afford to let it go against you. If you were trading an odds on fave, that would be just £3-4. I have actually tried always trading out if it goes one tick against me, although this can be quite frustrating if you get a bad run.
If you are doing larger moves for swing trading, then you'd need to adjust your level, or your stake, but its never bang or bust.
For those starting off in trading there is no crime is trading a few pound to start with to get the feel for it. If you see your bankroll increasing you can up it. Maybe do 5-10% of your bankroll - or more, depending on how confident you feel. If it goes up then great your return will get higher - if it goes down you are not risk everything and have a chance to try again.
Did that make sense? It did to me for a moment there...
