I can agree with the capitalization part. Even in starting a business, capitalization matters as it is a big factor to determine how long you'll probably last from the time you start. But the thing is, there's no such thing as trading without losses (in my opinion). No matter how tenured you are as a trader or even bots (especially), you cannot have 100% winning rate (unless you trade thinly or not often but then it's still no guarantee). It's actually the bait of most scammers in trading which many unfortunately still fall for - the guarantee of no loss.
