I didn't write yesterday, and I'll avoid the detail. Bitcoin FX isn't for investors with small amount of money.
If you want to throw money into bitcoin market, but what you have to bare in mind is that there is big amatur investors in the market who act thoughtlessly about their bigness. They drop the market into chaos.
So I bought actuals and decided rarely checking the charts. Hence I really scrificed 10,000 yen.
