The biggest mistake Ive ever made with crypto was I took a 1200$ loan in 4th quarter of 2021to invest in a meme coin that later tanked down to 70% loss, I was deluded with 100k BTC by December and also the beginning of a bigger altcoin season, I wish I listened to some advices on here instead of relying on some crazy youtubers, my own crypto journey started with huge loss i hope I will make them back some day, if you are new to crypto do not take me step.
You have made the mistake, what you need now is to learn from it and use it for future betterment.
There is nothing bad to borrow if you are a working class and will have no isssue to pay in time, or if you have other means to pay. But if you borrow and not having any means to pay back is when something is wrong.
You make a good point when you said if she's working class but the profitable cryptocurrency investment advice is to only invest the amount people can afford losing which I believe mean asking for a loan to invest in a crypto is never a good idea and this is one of the reasons why Binance has an issue with the UK government through their margin trading scheme
