Parting goals into long-term and short-term can also be applied to HODL, for example, let's take one year as short-term and 10 years as long-term and their goal is to accumulate 5BTC. It is important to have a goal of accumulating a certain amount for every year according to their risk tolerance then only it is possible for them to achieve their ultimate goal of accumulating 5BTC.
Short term goals are not classify as HODL. The word hodler, are used for bitcoin investors that keep their bitcoin investment porfolio for 4yrs and above before they can think of taking profit and the investment is still existing i.e they still have some bitcoin with them. While a short term investors is classified as a trader, the reason is because bitcoin investment is beneficial when you invest in long term to get a good profit compare to short term. The reason why short term are traders is that they can sell after one year and after that bitcoin price pumps 2x or 3x the year after they have sold, this shoes that they have missed out from the long term hodling profit.
Imagine that you are running a new business that you just set up and after one year when the business has not stand and it is still facing challenges to grow, you sold half of the business, will that business survive, ot because you have made little profit, you decided to sell the business to someone else and walk away with your capital and little income. If you have left the business and continue to manage it that your little profit that you made will be use to invest back into the business and continuously. A time will come after a very long time that the business has flourished that when you take a reasonable amount from the business profit, it wouldn't affect the business. Same way you should look into bitcoin too.
This is why have the long term goal plan and invest, then increase your bitcoin portfolio through DCA frequently, and you will see that you will grow in your bitcoin investment, the longer the timeline, the higher the chances of making profit based on the size of your bitcoin portfolio.
But if I can buy once a month with a pending order at the lows, and once a month sell at the highs (rarely too) - am I a holder or a trader?
@summonerrk, you are a trader and NOT a Hodler. This is because selling your bitcoin due to little price increase is a way to distract yourself from a long term goal, and it will be hard for you to reach your bitcoin target, if you have. You will also not be able to make a better profit got yourself at the long run and when you make the wrong decision about the market, it can lead to loss and you will regret it. Why I said so is because nobody can know the price movement of bitcoin accurately, and you can not always buy at the low and sell at the high, if it is always possible every bitcoiner will become a trader.
