How risky is day trading at the moment?
Its very risky nowadays because bitcoins value now are so volatile and very unpredictable, there will have a big pump and after a moment will be a big dump. Its more safe if you will just go for a long term trading and wait for your goal to reach for long term.
Day trading now is more like playing with the tiger's tail and you may not just get beaten but get eaten by the tigrish volatility of the market.
There is a huge instability now and a lot of uncertainty which is causing some pretty big fluctuations and unless you love taking risks, which can be profitable, I would not advise anyone to do it.
