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.
Hodling is a good strategy is a good strategy when investing in crypto. But it does not apply always to all projects. I have invested in many crypto based only on hype and held on to them hoping that their price will go up later on. But eventually most of those projects died down and I am left with worthless cryptos. I suggest really research about the long term potential of the project before holding long term.
