Hi Derunhan,
Here's adamgood. I understand that you are interested in playing live with other people via the internet and this is certainly the "million Turkish Lira question" as well as every other form of currency on the planet while we're under the suggestions to stay indoors 
I had a little bit of success while using jacktrip with my friend Phaedon in California (I'm in New York City). It brought an enormous (and rare) smile to my face to pick up my ud, start playing beyati and hear the sound of his kemençe in my headphones. There was latency but not nearly as bad as with Zoom or Facetime, Skype, etc. You ask about the problems of latency and it's simple, because of it, we slowed one another down but, still it was better than nothing. Also, his sound was occasionally "garbled" which hopefully you can understand the meaning...one moment it's pretty good then "glbblblblgblblbl" then good again.
Unfortunately, jacktrip has a steep learning curve. I tried to make my computers at home on my own network talk to one another with it and failed. So, I need to work on the again with Phaedon, troubleshoot and figure out solutions. But we're both a bit busy and need to find time in our schedules. When we again have success and have figured things out, I will be overjoyed and you'll find out about it on Facebook.
Meanwhile, I hope everyone here stays healthy and stays indoors. Our city here in New York City is already going through quite a bit but we're nowhere near what it will turn into in about 2 weeks time from now. I've heard that Istanbul and the rest of Turkey is heading for challenging times.
all the best,
Adam
