It seems you have forgotten the Bitcoin potentials, when it comes to investment Bitcoin is the best, with your dca strategy of accumulating Bitcoin no need timing the market, you buy at intervers regularly and buy wholesomely when there a downward trends. Bitcoin investment should be seen on long term perspective because it has the potential of appreciating it's compounded value over time.
You are right that Bitcoin is the best investment. Most of the major investors in the cryptocurrency market invest most of their money in Bitcoin. And if you invest in Bitcoin and are not able to hold it for a long time then your investment will have no value. So before investing in Bitcoin one should have a long term mindset and then invest.
Bitcoin investment is an investment where you can earn double profits if you hold the investment for a long time. Let me give you a small example to make this clear. Since you are here or on this forum, you must have noticed that in October and November 2023, the price of Bitcoin was below $30k. Since then, the price of that bitcoin has increased continuously until today I saw that the price of bitcoin has touched 60 thousand 357 dollars in the coin market cap. At this point, the price of Bitcoin is only $10k away from the new ATH. The only purpose of saying these words is that those who bought bitcoins below $30k and patiently held on are double the profits today.
