I understand what you're saying. Just remember that the mighty sword of leverage cuts both ways! Just as profits can be amplified - so too can losses!
It's also important to consider the demonstrable inefficacy of financial regulation within Australia. The repeated failure of ASIC to prohibit the inclusion of clauses that allow providers to, at their sole discretion, take the opposing side of the trade (i.e. bet against their own clients!), invent their own prices, alter margin requirements without notice, and even cancel profitable trades are amongst just a few of the things that lead me to question the wisdom of my continued patronage of this industry.
