Double Bass People tell that playing with a bow is good !

Get a tuner and really do get lessons.
I play arco all the time and the bow is like another instrument.
Bass played arco is beautiful and very fulfilling!
 
Unless you’re 12 and just starting out it’s unlikely anyone will ask you to play with a bow. Concentrate more on making and good clear consistent sound by plucking. That’s what you’ll be asked to do.
 
Yes man, that's some dedication ! Keep filming yourself ;)

I'd suggest you to do long tones, same exercise than you just did, but play all notes as long as you can with one bow stroke. Use all the length of the bow, and find the slowest possible stroke while still having a satisfying sound. I like to practice with a metronome to prevent me to go too fast, like the shortest I'm allowed to play is half notes at 40bpm.

A few lessons with a teacher (that knows german bow) could help you prevent tensions and injury in your right hand.

I strongly disagree with @Acoop . Maybe nobody will ask you to play with a bow. But people will ask you to play in tune, to play accurately, and to do that you need proper left hand technique and good ears, and the bow is an excellent way to practice that.

I've played exactly ONE gig on the bow, and yet I spend at least 40% of my practice time with the bow. It shows up deficiencies far better than pizz playing does.

Think of a professional football player. He might spend 20 minutes a week actually engaged in playing a game; how many hours a week does he spend in the weight room? Running laps? Stretching? Wind sprints? Blocking drills? I've never seen anyone slide a blocking dummy out on the field during an NFL game. How often do NFL players get called upon to stretch their hamstrings as part of a play? Lifting dumbbells seems not to be a major factor in either offensive or defensive plays. And yet they spend untold hours on PRACTICING THE ELEMENTS. Well, left and right hand position and technique are paramount to playing the double-bass. If you want to ensure you're shifting cleanly and nailing each note's position, you'll find that a LOT easier with the bow. If you want to build left hand endurance and weed out bad left hand habits, again the bow.

I'm sure there are many fine players who haven't picked up a bow in decades. But I personally would recommend the old-standard pedagogy including lots and lots of arco exercises and practice.
 
Study with a teacher. Bowing is an excellent way to learn how to play the doublebass. You can take a few lessons to learn the basics but concentrated long term study will get you results quicker. The comment that you will only be asked to pluck a bass is a self-fulfilling prophesy. If you can’t bow with a beautiful sound you not be asked to do so. But the moment musicians know you can bow you will get a lot more work. Bowing used to be a bit of a novelty outside of classical music but now it is practically expected. You can thank Edgar Meyer for that.
I am currently in Dublin. I took my bass to an Irish session and the room went cold as soon as they saw me. I waded in anyways and played a few set of tunes and they immediately warmed to me. But the moment I took out the bow the entire room changed. Just a few beautiful long tones and I had them in the palm of my hand. Beauty is beauty and people respond immediately when you can make them sound better.
