The $4-$4.7 area could be the turning point for the WTC /USD, yet its too early to say that with confidence. Further decline is possible, and $4 psychological support can be reached, even spikes below can be produced.
But all-in-all it is an interesting long term buying opportunity for the WaltonChain, that might result in huge gains over time. The uptrend confirmation could be the break above the $8 resistance, that only if price won't break below the $4 support. In that case first upside target is seen at $30, and if broken, new all-time high should be expected.
