The history of apple company, the third original owner who sold his share for $800 ended regretful for selling his share of the company because of no patience and belief that the company will soon rise and be known in the whole world. Now that $800 amount is already valued Billions of USD, now if you want to regret in the future there's no need to wait for it to come you can sell your tokens now for a very low price.
I was once own few Bitcoins year 2015 but don't have any idea that this will go trending online and will hit thousands in value, all of it was sold to a little value now I regret about that but already move on to that and don't want that to happen again. So, I am on HODL!
