Do not deposit large amount.

I would generally recommend starting with a minimum amount. It should be understood that a trader without work experience is likely to lose the deposit.

If you are trading with a new broker, I suggest investing with a lower capital for a few months till you have gained the proper knowledge and trust of the broker.

Because many scammer brokers block your withdrawals and do not reply or answer to the queries at a later stage.

As for me, this is a really important aspect for a trader. For example, I started with a broker from ExpertOption with the minimum possible deposit amount.
