Follow the market, that way you don't get hurt. A hodler is not just some special type of person that holds a coin and never dumps. A hodler is someone who believes in a coin and tries to have a significant stake in the project by accumulating more and more over time without getting too burnt by the market.
Smart hodling is the key.
Have you seen someone has invested a lot of money on september last year and he was loosing around 96% from his portfolios today? I guess you should see that. that guy gives a great lesson about never try to believe anything. Just try to do your own best decision to increase your money rather than only hold them all.
