The truth about crypto currency is that it is more about hodling, technically, crypto is hodling.
Most people that has been able to take profit from crypto currency trade or investment are those that have mastered the act of hodling.
Knowing when to hodl, when not to hodl is an important skill you need.
Not all the time hodling would work especially if you don't have the patience to hold that long.
If you see an opportunity to maximize your profit in short term too, why focus on hodling only?
I've seen a lot of traders who makes money doing day trading, I think we can call them successful too, and they don't need to wait for a longer time to sell as they can make profit anytime since they master the working technique in day trading.
For most of us who does not have enough knowledge and skills in short term trading and day trading, HODL is the best strategy that would fit for us, but Crypto currency is
"NOT" all about Hodling.
