You have to pay commission on each purchase / sale ??
According to this page:
https://crypto-bridge.org/#faqHow can I stake my coins? Are there fees?
The market fees are set to 0.2% per trade pair.
-- This seems a bit high given that binance only charges 0.05% if you pay your fees in BNB.
-- That said Binance "withdraw" fees are much higher than other exchanges.
Anyone know why the fees are at this level?
The staking fee is only 0.18 BCO. It's a one time fee, and was recently reduced from 12 BCO (it's related to the BTS fee to create a vesting balance). To stake, simply go to the stake tab using the wallet (there are instructions online).
The market fees are set to 0.2% per trade pair, but the market maker gets their 0.2% refunded PLUS a quarter of the other 0.2% (ie they get paid 0.05% to trade). The remaining fee, 0.15%, is divided up amongst the stakers.
