Hodling is just the synonym for long term investment without any liquidation.
In my opinion, there can be no other better way of making of money other than that of the holding of the crypto coins and that too coins like that of bitcoin etc. and that too for some very good period. doing so will help you in making of some good earning but for that you need to stay patient and that you need to keep a very good hold on your nerves for better results.
Certainly! Holding may or may not work for all of us in the crypto world. But in most cases, since market is moving unpredictability, holding is the mostly-applied specially when you want to gain higher returns or to recover losses. After all, it totally depends on how holding is being managed or viewed, what it can contribute for both success and failures in trading and what is the effective strategy to best apply. It's still best to study, seek advise from experts, and gain knowledge to gain profit.
