You're right; some people still struggle to understand because they want to make quick profit. I saw a post where someone claimed that he doesn't know if he is investing in Bitcoin or not because he doesn't understand how the market works; he has been investing for two years and hasn't noticed any changes, which demonstrates how greedy the person is. Bitcoin doesn't work like that; you have to be patient and the more you invest, the more you may expect a positive outcome. You can't just hold onto it for two, three, or four years and expect a significant profit in return.
Signature campaigns are not permanent but new campaigns keep coming every week. If your current campaign ends then you can switch to other campaigns. The aim is to DCA Bitcoin and signature campaigns are one of the best way of doing that because they pay you every week. it's a good way of investing 50$ or more per week in Bitcoin.
One more thing, if you are DCA Bitcoin then it doesn't matter a small dip from 124k to 113k because the impact of such small dips are ruled out in the long run. To understand that lets say fiver years from now price of Bitcoin is at 500k then it won't matter whether your have bought Bitcoin at 124k or 113k but what matter is how much you have bought at 113k, 150k, 200k, 250k and so on. Just don't pay much attention to small dips and keep accumulating Bitcoin.
