Have to agree with the sneering posts above.
How will you raise a child for 18 years if you can't even pay for the adoption but have to beg for bitcoins to finance it
As someone with significant experience in the adoption process I'd just like to add that asking for donations is quite common since adoption can be very expensive (far more so than having a biological child). Many families cannot come up with the large amount of up front cash and rely on friends, family, and financing in order to pay for the adoption services, even if they're quite capable of supporting the child later on.
Best of luck in your adoption Threshold!
