I think there is no need to wait for investing in Bitcoin. Because I myself bought Bitcoin when it was 25,000 and sold it at 40, thinking that this might be the highest price. If I lower it a little, I will buy it again. I kept waiting, but even after lowering it a little, the price kept increasing. I thought and waited a little longer, and after thinking, it reached 100, then I decided that there was no point in thinking anymore, I will buy Bitcoin with a part of my salary every month, so I started buying. Now I realize that I was wrong to wait. I think Bitcoin is an asset that may go beyond our reach in the future. So now is the right time to invest.
Waiting for bitcoin price to come down before you invest is the easiest way to quit bitcoin investment. This is because bitcoin is a volatile currency and has no established pattern of volatility. You invested at $25k and sold at $40k, I'm sure all these happened with the same year, probably 2023. You either weren't informed well about bitcoin or you were introduced into bitcoin by a bitcoin trader. Imagine if you still have that bitcoin by now, which is still less than two cycles, you could own assets in any much you wish.
There is no amount for bitcoin that is worth the next price of bitcoin. Even though you sell today at $200k, there are still higher chances of surpassing that amount sooner that you can imagine.
Surely you are not a good investor. You may have little idea about Bitcoin. I do not know how many dollars you invested at once when you invested. Maybe you invested without your emergency fund, due to which you had to sell your Bitcoin later or you lacked morale. Bitcoin is an electronic currency that can be invested for a long time. If you invest for a short time, there is little chance of getting a good amount of profit from it. People invest in Bitcoin to maintain the correct value of their money because the value of fiat currency is decreasing day by day due to constant inflation in the world.
If you want to keep your invested Bitcoin, then separate the discretionary income from the money you earn, excluding initial expenses and emergency funds, and from there continue to invest in Bitcoin in the DCA method.
You may not totally say that he is a bad investor when you are not sure of how he learned about bitcoin. Some of us were lucky to learn about bitcoin from the right source with the right orientation allowing you understand that bitcoin should be aimed at long term holding. Prior to joining this forum, I have always thought it's all about trading bitcoin. But in one way or the other, I couldn't trade due to fear of loosing my funds and not understanding the charts. Everyone has his early experiences in bitcoin investment and how he manages to get to the right track. I hope he does it better this time.
