oh yes you can rely on brokers, but first you have to look for information about brokers, their costs and history. The more old brokers, the more likely they are to trust them. I want to add something from the record, you do not have to invest a lot if you are only a year or coiuple from years of experience, it is very risky, though the margin you get may be extraordinary but it has risks involved. so I think 50,000 USD is a huge amount to invest. I think it's crazy to invest large sums, but if you have full confidence in the broker, then you can invest this amount but I think it can be a very risky risk for you.
