When and how can I use the mined coins?

You start getting the mined coins in 24 hours (after the main bonding)
The coins are sent directly to the main balance of your wallet (minus 15% the partner`s fee, see ‘How does the affiliate program work?’). After that you can manage the coins at your discretion:
Send them to a non-SPACEBOT exchange or a wallet (read ‘How to send coins from SPACEBOT’)
Or deposit them for bonding again (read ‘How to bond coins to SPACEBOT pool?’)
