What are the sources of the money you invested with bitcoin or cryptocurrency? Anybody here used credit cards?
Yes, I did. But it is certainly a huge gamble and not really advisable. When I first got into crypto I did some research on price history, and on what crypto could offer in terms of real-world use-cases, and then I used a 0% interest credit card to buy in.
Fortunately prices went up significantly, and I was able to take out my initial investment and pay off the card, and most of the coins I have now are due to that inital decision with the card. Of course if prices had fallen it wouldn't have ended up well. I think it was a good decision, but I appreciate that despite my research there was also a large element of luck involved.
It wouldn't have ruined me if prices fell to $0 and the whole initial amount disappeared, so if you do take a risk with a credit card then make sure you can cover it without too much pain if the prices move the wrong way. Certainly don't max out the card and spend as much as you can get hold of - that's just too much risk.
