It is possible for EU regulators can go after offshore brokers accepting EU clients. Just like US and Japanese regulators fined many brokers signing up their citizens.
Off-shore operations have been historically 'untouchable' by outside authorities, so I doubt that the EU the can do anything about them. Nevertheless, should this unlikely scenario play out, then TRADERS can also go 'off-shore' and it would be practically impossible to limit off-shore brokers to provide high leverage for their 'LOCAL' customers...
I would also add that the impending exodus of EU traders will jeopardize not only the traders (as mentioned before), but it will also put MANY retail brokers out of business, resulting in lost jobs and lost licensing & tax revenues.
