1. General FAQ

Can I deposit fiat currency like USD, EUR or Rupees etc?
No, we only accept bitcoin (BTC) as funds to deposit. When we are able to accept fiat money, it will be announced additionally. To deposit funds go to menu Account > Deposit where your BTC deposit address can be found. BTC can be bought on other exchanges like: Kraken.com, Bitstamp.net etc.

My deposit/withdrawal is pending. Can you speed it up?
Lately the Bitcoin network is very busy and many transactions are waiting in the mempool to be processed by the miners. We can't influence the Bitcoin network and thus we cannot speed up transactions. Also we cannot "double spend" withdrawals to be processed with more withdrawal fee. If you want your transaction to be accelerated, please try the BTC.com transaction accelerator.

2. Futures FAQ

What's a Futures contract at Deribit.com?
In our case a Futures Contract is an agreement to buy or sell a bitcoin at a predetermined price at a specified time in the future.

What's the contract size of the Futures?
1 contract is 10 USD.

What does Δ|Delta mean?
Delta is the amount an option price is expected to move based on a $1 change in the underlying (in our case bitcoin). Calls have positive delta, between 0 and 1. That means if the price of bitcoin goes up and no other pricing variables change, the price for the call will go up. Your total Delta position in the options summary is the amount your options portfolio value will increase/decrease dollar wise with each $1 move on the Bitcoin price.

What does Delta Total in the account summary mean?
In the Account summary you will find a variable called "DeltaTotal". This is the amount of BTC delta's on top of your equity due to all your positions futures and options combined. It does not include your equity. Example: If you buy a call option with delta 0.50 for 0.10 BTC, your DeltaTotal will increase with 0.40. If the bitcoin price were to rise with $1, the option would gain $0.50 in value, but the 0.10BTC you payed for it would also gain $0.10 in value. Thus your total delta change due to this transaction is just 0.40. Futures delta's are also included in DeltaTotal calculation. Equity is not. So depositing BTC in your account has no influence on DeltaTotal. Only opening/closing positions in your account will change DeltaTotal.
The formula for DeltaTotal:
DeltaTotal= Futures Deltas + Options Deltas + Futures Session PL + Cash Balance - Equity.
(or DeltaTotal= Futures Deltas + Options Deltas - Options Markprice Values.)
