To trade crypto on the Robinhood app, you are required to have an approved account with Bitstamp UK Ltd (BSUK). While you will still manage your portfolio, view charts, and place trades completely within the Robinhood app, the underlying crypto services are powered by Bitstamp UK. Bitstamp UK is a Robinhood-owned entity that is registered with the Financial Conduct Authority (FCA) to provide cryptoasset services in the United Kingdom.

The following are a few reasons why you can't place a buy order:

You don’t have enough buying power to place the trade. Crypto is non-marginable and can’t count as collateral, so you’ll need to have enough cash in your account to place the order.

You don’t have enough equity to reach your margin minimum. If you have a margin account (through Robinhood Securities) and are using margin buying power, you can't place a crypto order in your Robinhood Crypto account until you’ve paid off your margin balance.

Your account is restricted from trading. Restrictions on your investing account can result in restrictions on your Bitstamp UK crypto account. For example, if we’ve placed a restriction on your investing account preventing you from purchasing stocks, crypto purchases may be impacted until the restriction has been lifted.

A few reasons can cause your crypto order to not process or be filled. The following are the most common:

• The crypto moved outside the market order collar. All market orders for crypto are placed as limit orders with a collar. If the price of the crypto moves outside the collar, your order will remain pending.
• Scheduled maintenance is in progress. You’ll be notified in your app about any scheduled maintenance outages and their estimated duration. Orders placed during the maintenance window, they won’t execute until after the maintenance is complete. Note that all pending orders will remain pending during maintenance.

The price shown on the crypto’s detail page within the app and web classic is the mid price, which is the midpoint of the bid and ask prices. When you’re buying a coin using a market order, your order may execute at the ask price, which can be higher than the mid price.

When you’re selling a coin using a market order, your order may execute at the bid price, which can be lower than the mid price.

Crypto prices are volatile. To help protect your market orders against dramatic price moves, we adjust market orders to limit orders collared up to 1% for buy orders, and 5% for sell orders. Any price difference you may see between the estimated ask or bid price and the execution price is due to market movement.

Hashrate refers to how much computing power is used by a network (like the Bitcoin network) to process transactions. It can help you gauge the health and security of a crypto network.

For crypto traders, hashrate is an important measure of how decentralized a crypto’s proof of work network may be against hackers. The higher a hashrate is, the more difficult and costly it is for someone to attack the network. A sudden decrease in hashrate could lead to crypto platforms halting trading or delisting a coin to protect their customers.

Coin events are rare events that can affect the market for a coin or, in some cases, the coin itself.

Coins may be split into multiple different coins, on-chain transfers may be halted, or may have some other transformative action applied across holders’ coins. Because these are rare and specific events, there is no generic answer for what will happen, but we’ll inform affected customers as to what to expect as soon as we have the details.
