Hodling is not a bad thing to do.
Hodling can give you huge profit, but not at all times.
Hodlin in bear market can make you loose, if you are not careful of what to hodl, because not all coins are good to hodl for long at this time.
When you are advised to hodl, although it might be good, but let your consciousness be awakened, else you will be hodling and at the same time losing.
So hodl what you are able to follow up.
I like your advises but the cryptocurrency ecosystem sometimes cannot be predicted, sometimes you panic sell and it turns green and other times not... Cryptocurrency is still in its infancy
