Yes, it is a high risk and I don't think it is worth it. However, I see people who have hundreds of referrals without paying money and get paid a lot per month. How? I do not know. I tried a lot in this field but I never succeeded. I got 50 referrals on a site, but only one of them was workingNo, it is not really profitable, although I was looking at many that could be bought for less than 1000 sats, but they had really worked the page very little, it is like playing the lottery to buy a referral who later goes to work on the page every day when currently it's not doing it.
