By design of the system, the sell advertisement is only allowed to specify the minimum and maximum BTC/ETH amount in one trade, and your advertisement will operate until your available Bitcoin is exhausted. However, in some cases, you only want to sell a piece of Bitcoin you have, not all, you can use the following method:
- Activate 2-Step Authentication (if you have not already done so, you can see how to enable two-step authentication here).
- Go to "BTC/ETH Wallet", then create a withdrawal request to any of your personal addresses (but do not confirm Authy code to approve your request) with the amount you want to keep. As such, the balance in the withdrawal request has been frozen, and you can only sell up to your available Bitcoin/Ethereum. Remember to turn off your ads after you have sold your desired amount, when you want to re-use your frozen balance, just go to the history of withdrawal request, then cancel the request. Example: You have 10 BTCs, you want to sell 1 BTC only, you create withdrawal request with 9 BTC but do not confirm.
On the other hand, you can just deposit the amount you want to sell into your Remitano BTC/ETH wallet, and the rest you store in your wallet.
