Success doesn't depend on how much you know about Bitcoin or how many years ago you invested.
For me success in bitcoin depends on the quantity of bitcoin you've and how long you were able to hold before selling or taking profits. So it is a simple formula
More quantities of bitcoin + longer holding period = more success
Let's give another example: a person invested in
Bitcoin in April 2021 and his investment was a large sum of money at once. At that time, the price of BTC relatively high. As a result of investing a lot of money at once, he had no money in his hand. But it turned out that later the price of Bitcoin had decreased a lot. Here, if that person had not invested a lot of money at once in the lump sum method, but had followed the DCA method and bought it monthly or weekly with a fixed amount of money, then he would have been able to buy Bitcoin for less money in 2023 when the price of Bitcoin had dropped to twenty thousand. Therefore, his average purchase price of Bitcoin would have been relatively much lower. Therefore, it is most important to invest in the right way. There are many people, but they do not invest. As a result, despite being quite knowledgeable and senior in Bitcoin, they have made relatively little profit or many have faced losses due to not investing in the right way. Therefore, investing in Bitcoin is a long-term investment and patience is very important here.
This is why continuity is preached in bitcoin accumulation, if the investor lump summed on the high and continued accumulating bitcoin consistently using DCA, he would still have the opportunity to buy across the lows and who knows, if again he has a large discretionary income available then, he can still choose to lump sum on the dip and get a lot more quantities at a low price and add to his portfolio. This would help him to keep drawing closer to his accumulation target at a faster rate. If he goes for a long term, maybe 10 years, we will see that price he lump summed on is a good one.
One thing that is important to note is that the highs of 2021 is the target lows of now, so the investor still got into bitcoin at a good price. If bitcoin price in the future gets very high and he is still holding, then you would see him getting very good profits from his investment.
