Do you know that what makes most newbies to sell off their Bitcoin investment is a major price decline of bitcoin. For instance if they bought $2k bitcoin at once and when their is a decline in the market and their capital go from that $2k to around $600, this could trigger panic and the thought to salvage what's left. This could have been avoided if they were properly oriented about the DCA method from the beginning and they utilize it. If a newbie invest using the DCA method and there is a decline in the market and his capital didn't record a big decline, I bet you that newbie will not sell off his portfolio. He will see it that his capital is not badly affected.
It would obviously be the case of orientation and not having the clear idea on how these things happen in Bitcoin. Mind you, when there is a decline, it always depends on the position at which the individual had taken a buy and for someone who buys using the DCA strategy, you don’t always get to buy at a low, you could buy at a high price too. It’s always available funds determinant rather than the price on the charts. If this be the case, it’s always very unlikely that your capital wouldn’t be hurt on a decline except, in obvious cases where you’ve already bought a huge volume when the price was low and some worth volume while it was high. The high and low would tend to balance off profit/loss in price differentials.
