I'm buying ~500$ in Bitcoin every month with part of my salary. I have a stable job and my company is doing good. I'm wondering if it worth to take 20.000$ to buy 2 BTC now and pay the 500$ as loan installment instead of buying sats every month. I believe in the potential of Bitcoin to reach 50k in a couple years, but it wouldn't be possible to buy near half of BTC at the 500$ rate, so this would be something like an "advance". Hypothetically (but still possible in some probability), if BTC collapses and never recover from 8k, I would still be paying this loan for about 3 years but wouldn't starve or something like that, it would just sux for a while, since I still have another source of income. I know it's not the place to ask I will do whatever I think it's best, but if you were in my position, would you do it?
Something similar is available for Mutual Funds, you can either buy funds at one time or pay every month in Systematic Investment Plan.
But the problem in your case is:
1. Bitcoin is much more dynamic than mutual funds. When you buy all funds at once, it guarantees that you will make much more profits than buying every month because CAGR of funds is mostly positive. But in case of bitcoin, you never know when it is 20% positive or when 20% negative. So if you invest whole amount today, it may become very risky if btc fall in near future.
2. You are taking loan to buy coins. Thus, you will have an additional expenditure of interest rate. It will decrease your profit by certain percentage.
