For USDT-margined futures (long and short positions): Forced liquidation fee = liquidation quantity × liquidation price × liquidation fee rate. Fees are charged in USDT.
For coin-margined futures (long and short positions): Forced liquidation fee = liquidation quantity × liquidation fee rate. Fees are charged in the underlying asset.
Liquidation fee rate is generally about 1% to 1.2% for different products. You can find more info about our forced liquidation policy on BTCC’s website under the support centre section.
In addition, demo accounts are not made only for newbies, but also for experienced traders, to check platforms, conditions, etc… The better demo account will also attract large players.
You also have to check costs which are related to specific account types. There might be some other commissions or spreads which should be taken into account. Don’t look just for the costs of a single asset.
