I see many threads about how hard trading is here, but i don't think it's so hard to that you want to make it look like. I wonder is anyone here actually trading or have tried to trading, or is it just to fill the sign-campaign requirement?
A very good description of Trading.
What do you see here?

Trading is hard and it is easier to lose money than to get profit with trading. I think trading is very addictive and many people can not quit trading because they already addict with trading.
Trading is a tough journey like the chart you share and in this volatile market, with news, fud, trading is harder as emotion, psychology can be affected a lot. Investing is not easy too but if comparing to trading, it is more easier to get profit.
The challenge with investment is choosing a good asset. If you choose Bitcoin, you done a hardest part and the rest is holding it to get profit. It will be so smooth if you look at the chart in Log scale.
