As a holder you gain a benefit and greater returns then normal, depending on your luck that could be great but there is definitely a interplay or balance the deserve to hold for this benefit and the natural tendency of any market which rises to sell for profit taking.       If the price is going to accumulate from these holds and you are bullish about a rising population for FUN then maybe overbuy your target for hold and sell the excess to take profits.  This might be the best compromise, otherwise you'd have to calculate with ninja accuracy the correct time to sell, forfeit holding bonus or reset its progress anyway and gain the free cash flow.
  Obviously BTC does sell off from time to time, I do expect this to be a thing but I generally hold anyhow hence I didnt see it was too much hassle to have FUN also.
