No offence to anyone intended, but if a person loses their life savings, then they have not learned the rules they should abide by from the beginning.
Rule 1 - Don't invest money into Forex that you cannot afford to lose. If you do and find a losing streak, desperation will start to rule your decisions, not an unemotional mind - which is what is needed.
Rule 2 - Risk Management. If you have the correct risk management and place stoplosses accordingly, your capital WILL be safe. Do not chase your losses. They will come and must be expected, but follow your plan and you will ride them out. I, for one, decide to risk a % of my capital and adjust lot size accordingly. Never risk more than you are prepared to lose.
Rule 3 - Trade your plan. You need to have worked out a trading plan, and as such, most likely used it on demo for a period to get used to it as well as check its results over an extended period.
Rule 4 - Determine your exit strategy. Yes, you have a stop loss there, but what if you have a decisive signal that the trade is no longer valid?? Get out of it! Cut the losses. Likewise, what is your strategy once you are in profit? My last trade (last Thursday), I took half profit at a pre-determined fib level and moved S/L to breakeven, then went to bed, expecting the trade to continue. It reversed, but I had my protective stop in place and money already in the bank from it. Multiple people here on Babypips took exactly the same trade, but we all differed slightly with our exit strategies - but at least we had a strategy.
Please do not look at a trading plan being the be all and end all of your success or failure in Forex. Two people can take the exact same signals. One can become financially independant while the other can lose everything. The signal, or plan is only one small component of a much bigger puzzle. People make good money with a 70% strike rate. People lose money with a 70% strike rate. I personally know one person financially stable off Forex alone who has a strike rate between 40% and 50%. It is possible, if your money management is correct. He also is very aggressive in getting out of his trades when they reverse and let the winners run. Quite successful.
For someone who thinks Forex is a scam, maybe you need to step back from using real money to start with. Study Babypips and find something that resonates with you. Personally, I am a VSA trader. Others will call it voodoo but it works for me. Find that method that works for you. I'd encourage reading some as well. Have a look at Master the Markets (VSA Basics) and especially Trading in the Zone, which is more on thought process etc.
Don't give up. Keep persisting and learning. It is darkest just before dawn.
