You should post the details here first, it's rude to ask for help on something and just provide a link. However I might add, be careful not to go bankrupt because of this generosity offering $50, I mean come on man, the link says 10 BTC and you only want to share $50? Lol you even say maybe you'd give us $50 meaning it's not guaranteed that we will get that payment.😅
My thoughts too. At least the forum has enough space to accommodate whatever it is that's hiddeb in the privatekey link provided above. If really this was a problem that you're battling to solve, why not expatiate it here for us to help you. Must you have to make it look that you're also offering us a favor in return?
Secondly, aside from the above-mentioned, it is not just every link you want visit, hence the essence why photo uploads are provided here to help you explain your poin better. How I also wish there are some automatic tools here in the forum that verify links, that will go a long way.
Lastly, your level of uncertainty by adding a "Maybe" to the bucks you're offering will further disinterest other well meaning members here. I mean, there are a couple of generous experts here that could proffer a solution to your problem for free, but your statements could also easily chase them away.
