I agree with all posts here. FX trading is by definition not safe.
However, I can suggest here two safer ways to trade Forex:
1) buy a signal on mql.com which has at least 70weeks of history. You will need enough capital to gain around 1% per month minus the signal cost (~10k).
2) safe and slow one-way grid:
2.1) find areas in history where a trend (same candle color) on the 1D timeframe was the strongest. E.g. 4 candles and 5% between max and min.
Now compute the grid step as to be 25% of the double of the max-trend range:
E.g. 5%*2/4=2.5%.
Important: don't use lower timeframe to estimate the one-way-jumps. This is the most critical step in the strategy.
2.2) Now, enter e.g. a short position no matter when. Entry signal is irrelevant. Just do it right now in your demo account.

Use 0.01lot or max 1% of your account.
2.3) place limit sell order with 2.5% spacing above the first position. Set the order lot sizes as following: 0.02, 0.04, 0.08. (X2 the previous position in the grid.
2.4) exit all positions when the account is in the profit area.
The second strategy is considered as martingale and super dangerous. This is true but **only if you set the grid spacing too small.**
This happens quickly (also to me from time to time) because of greed and overconfidence.
Update: if you apply the 2nd strategy, you will suffer pain while looking at the eventual drawdown. Get used to it (see book bulletproof trader).
