"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 fort too long and didn'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.
hold is harmless as long as we can pick a good coin to use and maintain. for seniors I think if getting into the wrong coin will definitely be harmed though using the hold system. so hold also must be careful.
