  2. Fun and social
  3. SIPC insured ($500K in investments protected, and $250K in cash)
  4. Townhalls with CEOs of companies to ask questions

Important disclosures

Archimedes does not currently offer any financial advice. All content is meant to be for educational purposes. Crypto is a very risky asset and it isn't prudent to invest significant savings into a risky asset class.

From Public

“Zero-commission” or “commission-free” means $0 commission for Open to the Public Investing, Inc. self-directed individual brokerage accounts that trade U.S. listed securities electronically. Other fees may apply. See our Fee Schedule for more information.

This is not an offer, solicitation of an offer or advice to buy or sell securities, or open a brokerage account in any jurisdiction where Open to the Public Investing, Inc is not registered.

Open to the Public Investing, Inc does not recommend any securities. All investments involve risk and the past performance of a security or financial product does not guarantee future results or returns. Keep in mind that while diversification may help spread risk it does not assure a profit, or protect against loss, in a down market. There is always the potential of losing money when you invest in securities or other financial products. Investors should consider their investment objectives and risks carefully before investing.

The above content is provided for general informational purposes only. It is not intended to constitute investment advice or any other kind of professional advice and should not be relied upon as such. Before taking action based on any such information, we encourage you to consult with the appropriate professionals. We do not endorse any third parties referenced within the article. Market and economic views are subject to change without notice and may be untimely when presented here. Do not infer or assume that any securities, sectors or markets described in this article were or will be profitable. Past performance is no guarantee of future results. There is a possibility of loss. Historical or hypothetical performance results are presented for illustrative purposes only.
Investors should be aware that system response, execution price, speed, liquidity, market data, and account access times are affected by many factors, including market volatility, size and type of order, market conditions, system performance, and other factors. These risks are to be assumed by the customer. For additional information on data provided within the App, please see our Data Disclosure.

Investors should consider the investment objectives and unique risk profile of Exchange Traded Funds (ETFs) carefully before investing. ETFs are subject to risks similar to those of other diversified portfolios. Leveraged and Inverse ETFs may not be suitable for all investors and may increase exposure to volatility through the use of leverage, short sales of securities, derivatives and other complex investment strategies.
Although ETFs are designed to provide investment results that generally correspond to the performance of their respective underlying indices, they may not be able to exactly replicate the performance of the indices because of expenses and other factors. A prospectus contains this and other information about the ETF and should be read carefully before investing. Customers should obtain prospectuses from issuers and/or their third party agents who distribute and make prospectuses available for review. ETFs are required to distribute portfolio gains to shareholders at year-end. These gains may be generated by portfolio rebalancing or the need to meet diversification requirements. ETF trading will also generate tax consequences. Additional regulatory guidance on Exchange Traded Products can be found by clicking clicking here.
