HODL is very dangerous especially to those that bought at the top. Thus when the general market goes Red, they fall in loss then Hodl with a hope of the coin going up again but most won't times and if care is not taken, the coin goes down in value more and more.
"Hodl" is word used to much in crypto space but i think hodl can be dangerous for newbies mostly they will be shilled and hodl a shitcoin or hodl a solid coin for too long and wouldn't sell when time was right you will end up like me as there was time when i could buy tesla now i can only buy honda.
