 This script is not a full replacement for the incredible service Bittr offered, but it's a start:
 Automate your Stacking Sats process by regularly placing buy orders using the [Kraken API](https://www.kraken.com/features/api).
 
+Holding significant amounts on an exchange is never a good idea. You should regularly take ownership of your coins by withdrawing to your own wallet. This can either be done manually or it can be automated. The script provided here will only withdraw to a previously defined Bitcoin address if the relative fees do not exceed a certain limit.
+*It is optional to run the witdrawal script.*
+
+**Example 1**
+- Max. relative fee: 0.5%
+- Fixed Kraken fee: ₿ 0.00050
+- Balance: ₿ 0.06000
+- \> No withdrawal since fee actual (0.83%) is too high
+
+**Example 2**
+- Max. relative fee: 0.5%
+- Fixed Kraken fee: ₿ 0.00050
+- Balance: ₿ 0.12000
+- \> Withdrawal executed since actual fee (0.42%) is low enough

+## 🔑 Withraw sats

+It is recommended to run the withdrawal script every time you stacked sats:
+
+```sh
+npm run withdraw-sats

+Since it can take a couple seconds or minutes for your order to fill, you should run the following script maybe a couple hours later after your `stack-sats` script ran. Just set up a second cron job which executes the following script.
