I haven't watched the complete video... just the first 10 seconds...
This guy is showing a newpac usb miner... You can find them on sites like this one:
https://www.bitshopper.de/en/shop/sha-256-miner/usb-miner-bitcoin/newpac/The device hashes @45Gh/s (maximum... it is rather difficulty to make those usb miners run consistently at those speeds), and at these speeds it'll draw close to 10 Watts.
Let's assume for a moment, you're able to get it running @45 Gh/s whilst it draws 7 Watts and disregard the power consumption of the rPi (or pc) you need to connect it to. Let's also assume you only pay 5 cents/Kwh for your power.... These are huge assumptions: you'll probably won't keep it running @45Gh/s consistently, if you do it won't consume only 7 Watts, and you'll probably pay way more than 5 cents/kwh
Let's plug in those numbers at a mining calculator:

Nor the investment of an rPi).
Even if you disregarded electricity completely, this gear would still only make 2 cents/day...
