Kraken trading

Your machine can connect to an exchange so that bitcoin is automatically purchased at market rates with each bill that's inserted. In this way the price volatility of bitcoin is mitigated.

Kraken trading is supported for Bitcoin, Ethereum, Zcash, Dash, and Litecoin on all fiat currencies.

Flow with trading

When linked to an exchange, the flow is: user inserts bills, machine places buy order with each bill inserted, coins are sent from the machine's hot wallet to the user. The module will purchase the same amount of coins that is dispensed to the user.

For security purposes, the admin does not initiate a withdrawal of coins from your trading account to your hot wallet. You should periodically top up your machine's wallet by sending it the coins which are purchased on Kraken.
