US-based bitcoin exchange Trucoin has increased its customer's daily purchase power to an "unprecedented" $1,000.

Trucoin’s announcement comes at a time of rife competition as companies selling bitcoin in the US try to capture the market.

Circle, a competitor in the space, has a weekly limit of $2,500, which can vary depending on the amount that is purchased. Purchases made with credit cards, though, are capped at $500 a week.

Coinbase, which recently launched its own exchange, currently only accepts Visa payments. The company sets a limit of $1,000 a week for accounts that purchase up to $50,000. Those who purchase up to $3,000 are subject to a $100 weekly limit. 

Brent James, Trucoin's executive vice president, said:

“To our knowledge, we are the only company that has been able to successfully allow consumers to buy this much bitcoin with a debit or credit card.”

Additionally, the exchange recently expanded its coverage to include California, Pennsylvania, Missouri, Utah, Nevada and Delaware, bringing its total to 32 states.
