This reminds me of a friend of mine who used DCA and is now making significant profits. Initially, he refused to do DCA, but now he truly feels the benefits.

Sometimes when I see people making posts relating to making significant profits it gets me wondering the level of their Bitcoin accumulation stage and how long they must have been holding Bitcoin to be talking about making significant profits, the real fact is that it is good talking about profits when we are still in the accumulation stage and have not gotten to or some where close to or over accumulation and maybe has hold Bitcoin for at least one to two cycles or more if not the focus should be more accumulating more Bitcoin instead of talking about profits because from post I doubt if your friend has gotten to this point of which you are now talking about making significant profits.
Sometimes I feel that even while doing the DCA one should still look at the prices especially if we know that we are in bull market and the bitcoin prices are on the higher side.
If you ask me I will try to invest more during the bear season while as the price increases my DCA amount will start to lower. I think this is call smart DCA because in this case you will accumulate more at lower prices and it will give you more returns.

I don't consider this as being smart, modifying your DCA amount sounds retarding to me because the overall market is unpredictable, there is possibility that the price can keep going up after you must have kept some money you should have used together to buy Bitcoin making you to have missed good opportunity. You don't have to consider such approach in one direction.
