Are you really certain that this will really happen in 2 years time period? It's all about calculation and prediction, which are never 100% accurate. And what about risk management?
Let's say that OP did a good choice, choosing the time and price, and now he's making profits. Let's imagine the same scenario with a different user who will buy after watching this post and getting inspired from it. I am not against HODL and long term investment. But just imagine, someone else took some huge loan in order to invest in bitcoin.
The bull market starts, and as we all know, it doesn't stay high for a long period of time. It will drop again. What if the price drops below your buying value?
How long are you going to HODL again? And how are you going to repay your loan with interest? That's why it is best to invest what belongs to you and some small amount of loans that you are able to repay in short time in this event.(Taking loan for BTC investment is never a good idea).
I was only judging based on the OP's statement. But honestly, I also fall into the category of the scenario you gave; the difference in my case is that I did not borrow the money I invested with. During the 2021 bull market, I bought a little fraction of Bitcoin, and my hope was that Bitcoin price could bump to $100k, at which point I would just sell and take my profit, but my plans were futile because the price could not get to $100k and we went into a bear market in 2022. In the OP's case, I can say he's lucky, but I will not tell any of my friends or anyone reading this not to invest in bitcoin. I can only advise them about the risks involved in taking out a loan before investing in bitcoin; if they choose to go ahead with it, I can't force them to stop.
