trust me, you make the best decision.. someday surely Bitcoin will be very expensive even exceeding $ 20k, but we don't know when (it could happen in 2020, 2021 or 2030). HODL is the right choice when you are not a reliable trader.
Holding will surely get you good profit, but for the same we need the patience as well the financial stability to keep hold of the bitcoin. In most of the cases, people with more hope keep on holding but their financial need make them to cash it out. This way even with the process of holding the benefiting people were the rich ones. Very few common men get to be lucky to profit investing on low price altcoins and holding for years.
