in ways it depends on the risks you are willing to take. you already seem to be aware of the risks and you don't mind ending up paying the loan while in loss so i'd say go for it specially now that price has come down so with $20k you will be able to get about 2.46 bitcoin instead of 2.
but generally speaking i personally try to never invest what i can not afford to lose and definitely not with the money i don't own (loans for instance) i believe lower risk lower profit is better than higher risk higher profit for me.

Have you ever thought that what if what you were thinking of would be the opposite. What if bitcoin didn't reach that price after a few years. Consider your options and potential risk that you are going to take. Applying for a loan and paying interest would hurt your financial status a lot. Do not be to confident that since you have a stable job you could make such a drastic decision. Nothing is permanent. Just invest what you can afford.

As a principle of mine, I make sure that I don't ever go for a loan to do any type of investment because there is a 50% chance of losing it all but OP seems to have a stable job and it wouldn't really hurt that much if the price of bitcoin seems to go down in the near future if heshe is patient he will reap the profits.

Don't. Even though it has the potential to reach 50k, loaning for it isn't that reliant. Just continue your buying spree every month and don't bother. Bitcoin is a type of investment, and using loans to pay for that investment isn't that worthwhile in my opinion. Of course, if you could pay the loan without affecting your current performance in life, do as you deem fit. These are just my advice and you don't really have to stick to it, but do take it into account.

It seems to me that it’s better not to get involved in loans, but, as before, invest in bitcoin for $ 500 every month. Firstly, I’m not sure that in a few years Bitcoin will increase in price much. Secondly, it’s dangerous to get in touch with loans, and you still have to pay certain percentages. I see that everyone here is also against taking a loan to buy two bitcoins now. Better not to take risks, but to invest constantly. Even if the price of Bitcoin falls, with the same amount of investment, you will buy more Bitcoin.

You could see this 2 ways though, in one world he gets a loan in order to capitalise off the falling BTC prices and then they go up in a couple months, he can either sell BTC so he can repay the loan and make some money, or just keep it.

I recommend you to think this through, but being a safer person myself, I wouldn't take the loan, just be happy with the amounts of BTC you have so far, and keep working on the 500 a month.

Please avoid buying bitcoin using loans, it's risky as we don't know and we can't predict when and if bitcoin will still pump up or die, it might happen at any moment. If you have a stable job then you must continue what you are doing and buy worth of $500 monthly in that way if you lose you won't feel broke at all since it's all spare money.

Do not loan, it is not practical thing to do. Because bitcoin will not pump so easily, it takes months before it is really unstable. Your loan will have an interest monthly make sure if you got your loan you will not go broke, since you have a job use your salary instead. Take the half use it as your daily budget then the other half use it to invest.

I strongly do not recommend a loan to buy bitcoin, it is a very careless action to do. Because investing principle basically use your
extra money.Remember when we agreed to loan money, it means we are obliged to pay installments without being late.But the problem is sometimes
there are sudden needs that require money suddenly. Later your finances can fall apart.Let's think about the worst if bitcoin hasn't
gone up, and you have a sudden need right then and there.Because I've experienced something similar, using a bank loan to buy bitcoin.
What happened was I was fired from where I work, then the price of bitcoin actually dropped. I decided to sell everything, but I couldn't
close my loan, The end have to sell one of the assets that I have, which is the car that I have. Since that time I promised not to borrow
money again,especially for needs that are not urgent.
