Is the recommendation to HODL Bitcoin, to hodl forever, or until the owner really, really needs (or really wants) currency for something important - with the intent to only sell a fraction of the BTC he has and continue hodling the remaining?
Its just like doing a business, some will like to sell at $5 interest while some may prefer selling at $15 interest or even more depending on how long they may wish to hodl until they have a customer to buy at their selling rate, once you're able to hodl bitcoin and also make some profits on it, then you may decide on when to sell and at what rate you wanted to sell base on the current market value on bitcoin, if otherwise, you can continue to hodl and as the market keep increasing, then you keep earning as well, some may also choose to buy the dip and sell and continue in this circle.
