Hi Sovereign People New World Order - in future it's break down your support requests and create a new discussion post. It is easy for things to get missed with you ask questions as a reply to another post.
With relation to Jitsi server - there is not cost for this, a free service provided by Jitsi.org - if you want added security, you can establish your own Jitsi Meet server, but for free you can use the default meet.jit.si
With regard to deleting apps - first you must deactivate the app,
then once the app is deactivated if you use the Manage Launcher want (pictured) you will see that the deactivated apps have an option to delete. Be careful when deleting apps, as you will lose all associated data with that app.

Also to use Crypto you should try UNA Credits - which is essentially an internal UNA currency, where you buy and sell currency and charge commissions. We have integration with Bitpay, which allows users to pay in Bitcoin please see providers in Payments app.

Hope this helps.
