If you can’t go long (open a ‘buy’ position) on cryptocurrencies such as bitcoin, ripple, or ether, the most likely reason is we have reached our internal limits on these products, and so the market is set to ‘unlongable’. This means we are unable to accept any new long trades either by phone or online – but you’ll still be able to close existing positions.
Due to the risks associated with cryptocurrencies, there’s a limit to the total amount of physical cryptocurrency we can hold as a business. When this limit is reached, we are unable to purchase more cryptocurrency to hedge your position.
This is when a market will be set to unlongable. And because we don’t know when we’ll be off of our limits, it’s not possible for us to estimate when the market may become available to trade again.
