No doubt learning and improving is usual thing in every life no strategy is bad DCA, lumps sum the most important is to buy and hold for long time , I can remember despite how many person may say about the DCA one of my friend who invest in Bitcoin told me because of his engagement with other things he prefers lump sum that he don't always have time to buy in parts because it seem as a way of monitoring his investment since his motive is to buy and accumulate for Long he buys and remove his feeling just one till he plan buying again to add up, I see that what he feels and the knowledge he conceive towards usage of the strategies become his guilds DCA is good for all mananer of investor but some still tide it to choice as it depends on knowledge and what the investor may prefer at the moment he wants to buy correlating this your statement is hundred percent correct.
If you hodl appropriately, then in any case - you will get boons from your investment as time goes on and cycles change themselves.
It's about knowledge, risk management, and doing it systematically.
Of course, everyone has different ways of buying BTC. Of course, everything is good and it's true that the important thing is to be able to hold BTC for the long term because even if you use DCA, if you can't hold BTC for the long term, you certainly won't make a profit.
You are very correct the most important thing is to hold Bitcoin for long term, in other for you to make huge amount of profit with a relax mind then you have to hold for a very long term, and for me I will suggest 10 to 20 years but you can do from 5 and above if you wish, it will even be better if you use it as your retirement plan, one of things that is seen as something that can cause you your money in Bitcoin investment is it's volatility however long term holding is the only thing that can defeat it, so as a Bitcoin long term investor you don't have an issue with Bitcoin volatility, and yes there's risk also in long term holding but the is low compared to Bitcoin trading.
As a Bitcoin long term holder you can still decide to try Bitcoin trading but it should be done with 1% of your discretionary income, some set of long term holders trade for fun someone told me instead of him to gamble as fun he rather trade Bitcoin for fun and still continue with his long term consistent accumulation and holding, however if you know it will cause you restlessnes then focus on your accumulation and holding.
Bitcoin is not a Ponzi scheme if you want to invest and make good amount of profit then hold for long term.
