Different opinion? I bet no reasonable opinion can be contrary to the DCA investment approach, the only suggestion here will be another investment approach and not the condemnation of the DCA approach as the approach is not the only way out in investment. Aside from this, DCA is a very good investment approach that fits in for the poor, average and the rich, it helps you average both your risk and earning possibilities. Mind you, with this approach, you should know that you would rather be conservative, so the aggressive investors or the most lucky ones might gain more than you, but still, you will average the pains of the bad market behaviours and also average the benefits of the good market behaviours which make the DCA approach unique because either way, you will never miss out.
I think another one of the advantages of DCA is that you can simply automate and forget about it.
That way you will simply invest more and more over time without thinking about it.
That's usually the best strategy when investing. Simply putting more and more money in it over time and never touching it.
DCA method should be done in such a way that only money has to be invested in Bitcoin, and this investment has to be for a long time. There is no thought of selling bitcoins from this investment. But usually this Bitcoin DCA method will follow the basic needs of the family and with the extra money, because the more the investment, the more profitable it is because in the future the price of Bitcoin will surely increase several times more than the current price. Note that those who have done the DCA method since 2013, and have played holdings have accumulated and held the highest Bitcoins ever. So if you want to hold Bitcoin then you must hold Bitcoin for a long time and keep investing regularly.
