I think DCA strategy is easy and risk-free for new investors. If he has a reliable source of income, he can save Bitcoin with extra money at the end of the week. Alternative income and patience are more necessary to run a long-term DCA. Many new investors save fiat to grow their fund but if he can save Bitcoin at the same time, he will get higher profits. Buying altcoins is definitely riskier than Bitcoin. It is wise to expect profit by saving Bitcoin at the end of the year, but there is a possibility of losing other alt currencies.
That is a mistake because no matter what the strategy is in collecting bitcoin there will be no such thing as risk-free especially when talking about investing in bitcoin which we know the risk is there so doing with several different schemes from the purchase plan will not remove the risk that is owned so it is not too suitable to say the purchase method will make us free from risk.
But maybe it will still be acceptable when we say that this is one way to further minimize the risks we have because regardless of the increase or decrease that occurs as long as we are consistent with the purchase plan made with DCA regardless of price then at least we have some things that can still be used as a minimization of losses especially if the goal is long-term.
So it is not too suitable when saying investing in bitcoin with certain methods will be risk-free because the fact is that nothing is really like that. Risk is still risk where when in bitcoin (investing) then we realize that risk will always exist.
