Excellent!!! Excellent !!! Excellent!!!
Here's some comments as I watch it scene by scene:
Leave the "Emmanuel Abiodun" tag line up longer (at least 10 seconds) before you cover it with the "$17 million" tag line so the viewer can ID the guy. Currently you just flash this for three seconds and the viewer wonders what they missed and didn't have time to read.
Don't make the viewer's eye shuffle back and forth over three short lines. Center in the screen a top line that says "Bitcoin network:" and below that a SINGLE LINE centered on the screen that says "7 Transactions Per Second (TPS)" - all words with initial caps, bring the two parens as close together as possible. Pop the Bitcoin network line in first, the fade the TPS lin in a few moments later. The blue outline script is perfect - brrr!
I would reedit the overlays and the video in your next sequence a little. The musical opening is perfect. Slowly fade in the top line, "He's Mining NXT right now" using the the contraction. Just as the phone becomes visible (because you've reedited the timing of the scene a little), fade in a new second line in the middle of the screen, "On his smartphone". This works because the viewer is mentally asking "How?" from your first question, and you answer that explicitly with video shot so the phone is perfectly positioned below the center line talking about the phone. After a beat you fade in a third line at the bottom (in the same orange outline text - drop that yellow solid text), a much shorter version of what you say in yellow: "NXT. $300 per day for 7 TPS". Hold that for a beat, then fade in two new top green lines: "Mine NXT on your" and "smartphone or Raspberry Pi". (Note the "y" and not "I" on "Raspberry".
Then cut these two top lines and fade in your " Iceland/ Bitcoin" lines. Again, I would shorten the Bitcoin line to a single line of "Don't waste energy on Bitcoin" and just leave out the word mining at this point. Shift the emphasis from the mining to the total coin itself.
In general, try to make the lines as short as possible and avoid having to make the viewer cycle their eyes back and forth.
I suggest the following short lines (and only short lines) for your overlays:
*******************************
Bitcoin network:
7 Transactions Per Second (TPS)
He's mining NXT right now
On his smartphone
NXT: $300 per day for 7 TPS
Mine NXT with your
smartphone or Raspberry Pi
NXT: $300 per day for 7 TPS
Don't freeze in Iceland
Don't waste energy on Bitcoin
NXT:
100,000 TPS

Short lines stick with the viewer. Long lines distract them from the video while they figure out the long lines.
This is REALLY GOOD WORK, Salsacz. Congrats!
If I get to speak in Texas, I will leave this video looping over and over with no sound behind me on the screen during the 20 minute audience question and answer session....
