So basically a conclusion to all your article can be put shortly people who are losing money are losing because of no cut losses determination.
I would like to disagree with that it is relatively true but not entirely, as you can see people who are losing the most are basically not buying in the right time and selling in the wrong time, if a person keeps buying high and selling at the cut loss level which is basically buy high sell low, he will also be losing money, a good trader will always try to play it safe and think before investing, as in buying very low relatively to the chart and not buying in a hyped bump as the outcome of a bump most certainly will be a crash after a while.
so I would rather say not only stop risk strategy , but an entirely weak based strategy with the idea of simply i will buy and hold regardless of the buying rate according to the chart (all time or monthly or weekly even),
here are steps to correct the issue if you're not doing good as a trader.
1) don't buy coins which are not at low level, or at least no reason or inside news known to buy
2) before buying a coin don't make a gamble reaching x10000, and set a certain percentage of selling you will be satisfied at example 10% increment.
3) before buying you need to set a stop risk level which as you mentioned should be determined before even buying.
4) if you're planning to buy a coin and hold it even for a few days, you should know why it's valued like that and who/why the price is increasing as it might be a bump and dump coin, more often those coins will get you good before you even know it.
Edit: and as I noticed you're following the calls of the website you're promoting, you should always carry your own research and analysis of the chart even before buying, doesn't matter how good their calls are.
