For investment, "not" start investing with a small amount, start with half of the amount you can afford to lose. First of all, a Bitcoin investor should gain a basic understanding of Bitcoin, gain knowledge about the nature of Bitcoin's short-term volatility, and gain knowledge about Bitcoin's long-term potential.
So, for a new investor to start investing in Bitcoin, he should first gain general knowledge of Bitcoin and start investing through DCA, and invest the amount of money he can afford to lose in DCA. He can start investing in this way at first, and gradually learn about Bitcoin and gradually prepare emergency funds and reserve funds (while keeping DCA intact).
It should be remembered that you will not be able to profit from Bitcoin investment in a short time, and Bitcoin will never guarantee you profit, but there are many opportunities to profit from Bitcoin if you hold it for a long time, and for that you must be hold bitcoin with DCA for 8 to 10 years.
Is it really a must to for investors hold bitcoin for 8 to 10 years, before someone can see profitability in the investment? I think someone who is able to hold his bitcoin for a full circle stand a chance to see some profits. And if the investor decides to take part of his the profit he has made over the 4 years, he is not wrong. When you use the word must, it now looks as if 8 to 10 years is the only acceptable number of years for someone to hold bitcoin before they can profit from it. The reason why they say invest only money you won't be needing for the next 4 years in bitcoin, is because after 4 years you can do some evaluations to know if you can take part of your profit and attend to some of your human needs that must have come up over the 4 years of your investment and waiting. Yes it's true that if you hold your bitcoin longer for 8 to 10 years, you sand a better chance of bigger profitability. But that's now a choice that each investors have to make, after holding up to 4 years. To continue holding their entire portfolio or to take part of their profit and still continue with their DCA for the next circle.
I don't think it is necessary to put a duration of holding that an investor will see profit but it is advisable to hold for at least 4 years as this is enough to see two of the major seasons that Bitcoin go through base of the data we have about bitcoin. This is the minimum though, the most important thing is that the longer the hold, the better and more profitable the investment, do the investor should endeavor to hold for reasonable length of time to ensure maximum profits can be seen.
Some are not just holding for the profits rather as a way of accumulating wealth for the future. This class of holders does not worry about selling within the market cycles and will continue to buy more when they have discretionary income.
