I'll post the comment shortly with your name attached to it.
As a side note the request was for one or the other as collateral not both unless your paying the higher ask at a value of 0.05BTC each.
If you paying the lower amount you can chose the hashflare or the sr.member account.
Again: your hashflare earnings worth a few cents per week. Your BTCT account wont even possibly cover the 0.055 in a reasonable period of time if we try to sell it higher than that..
The hashflare would help (if you default) to limit the loss.
Let me know if you need this loan, i'm going for a coffee break.
The cost of the mining equipment purchased on HashFlare is $38 at today's prices (inclusive of any offers or promotions that are currently applied to the costs) not including whatever it can mine during it's lifetime contract.
Account makes an estimated 18k - 20k satoshi per day (after fee's I earn 5.4cents per day for sha-256, 3cents per day for script and 1cent per day for etherium) and a small amount of ETH, which is still mining away while you have control of it.
So even if I didn't manage to pay in time (which won't happen, guranteed) you would have the 40k sats currently sitting in the hashflare account and the $37.25 worth of miners which would easily cover the $24.83 cents I'm requesting.
