Sorry for the bad English. Could you answer the question?
Very doubtful. I've got 18 6-core Opterons @ 2.4Ghz and I get about 12-15 coins on most days. A Pi or an Android ain't gonna get much.
What's your hashrate with this?
About 1 megahash total.
Well, if 18 6-core Opterons run with 1000 KH/s, each one of them should run with ~56 KH/s. It's ten times my Pi3 hashrate (5.6 KH/s).
If you make 15 coins in a day, each 6-core Opteron should make 0.8 XMG. I made ~0.09 XMG with my Pi3 in my first day mining. Your numbers are consistent with my results and the guy's video seems to be very unrealistic. Big thanks!
Check the videos date. If it's a few years old, it could be quite accurate.
BTW, about mining with a Pi. Make sure you add a heatsink and check cpu temp with command "/opt/vc/bin/vcgencmd measure_temp" (without quotes) every few minutes for the 1st hour or so. Otherwise you may end up with burnt PI.
The temp varies between 77ºC and 80ºC while mining. Is that risky?
