    1. Hosting on your own hardware. It can be a Mini-PC like a Raspberry Pi. The costs for the hardware (~35€) and annual costs for power (~7-8€) are low. Keep in mind that your internet connection might be limited and a Mini-Pc is not ideal for a large users base.
    2. Run your bot in a Virtual Server/dedicated root server. There are many hosters out there that are providing cheap servers that fit your needs. The cheapest one should be openVZ-Containers or a KVM vServer. Example providers are [Hetzner](https://www.hetzner.de/ot/), [DigitalOcean](https://www.digitalocean.com/),  (are providing systems that have a high availability but cost's a bit more) and [OVH](https://ovh.com)

+Please use ```execute()``` instead. 
+Example:
+```java
+SendMessage sn = new SendMessage();
+//add chat id and text
+execute(sn);
+```
+
+If you extend ```TelegramLongPollingCommandBot```, then use ```AbsSender.execute()``` instead. Example:
