this is just martingale
Two things here....
1) You have no idea what you are talking about in regard to the account being martingale. Because it is clearly NOT. The trader is using only 0.01 lot sizes which is easily verified by reviewing the trade history which they have left open for viewing.
Martingale systems use a increase of lot sizes with each iteration of entry when providing coverage on a previously bad trade.
Example: lots 0.01, 0,02, 0,04, 0.08, 0.16, etc etc etc
2) It's a demo account so it's pointless to even discuss it. Demo accounts have no financial value and are therefore useless.
This is not my endorsement of this account, but rather a simple observation and consideration of the actual facts.
If you want to be profitable, make profitable trades.
