Question about this collateral

[FanEagle]

Ok, I'm just wondering, since nobody wants to tell me how much they can worth, If I have 500K Failcoins, how much could be the corrispective in btc?
Let's say I'm asking you now for a loan, how much would you like to give me to being able to be covered by the collateral?
If the collateral I'm offering is useless just tell me

Edit: Atm I'm not searching for an actual loan, just need to know if I can use what I earned for the job

I would not accept that coin as collateral

Collateral is worthless in this scenario:

Here you can see that there is literally no demand.  Over BTC5 is trying to be sold at the rock-bottom of 1 Satoshi, and there is not a single buy order up.  If evaluating a loan, you'd be better off looking into a lender willing to make it without collateral.

Ok, just to know what big mistake I did mining them.

It wasn't necessarily a mistake except in hindsight. You took a risk and it hasn't paid off. That's how risks work.
