well
big mistake .
i have more than 10 big mistake, the only i remember when i buy about 500k TRX with 3,2 eth on etherdelta.
then i sell too fucking fast , actually i can get x10 or 20 or x30
but i am too hurry to take x2 profit.

sad right ?

That is the reason why the volatility of the market is really important and most of the professional traders do really like this kind of growth in the market in order for them to get the best price they are intended to have.
The volatility only good if you can get into the right time, otherwise, it will be a struggle for anyone who wants to adopt this for other purpose than trading or investing.
But however, no need to regret, even I missed the ETH train when it's still few dollars and now has become hundreds, if I just investing huge money into it, I could've been a millionaire but I'm not, and maybe it's my fate LOL.
