Securities in your brokerage account are held in custody by Vanguard Brokerage, a division of Vanguard Marketing Corporation (VMC). VMC is a member of SIPC, which protects securities customers of its members up toR$500,000 (includingR$250,000 for claims for cash).

Vanguard is well known for being a leader in low-cost funds, but its brokerage offering may also be a good fit for long-term investors. You'll have access to thousands of commission-free ETFs and no-transaction-fee mutual funds, allowing more of the return to end up in your pocket.

Software-generated random numbers only are pseudorandom. They are not truly random because the computer uses an algorithm based on a distribution, and are not secure because they rely on deterministic, predictable algorithms.

But good random number generators don't have any clear pattern to their output, making finding which page of their codebook they correspond to very difficult.) There is no limit to the size of the codebook that algorithmic random number generation can support.
