[I'm not a hater of dropcatch, I'm still using their service]
yes, it is possible, it doesn't need to spend that much amount to beat dropcatch, look at the way Nsol working i believe they don't even had that much registrar accounts but they are using different strategy to beat others even succeed for years.
once i was nearly beat Dropcatch, successfuly catched a .org domain and hold it for a week but DC approached the PIR, the registry hold the domains for few days for investigation, after the investigation they gave the domain to DC(we don't know what happended inside the registry level but we need to respect their decision) finally the registry left a msg to my registrar, "double registration happened to the domain "same second' so the registry consider it as an internal error, dropcatch registered the domain before you in few microseconds ahead. so the registry award the domain to DC, i believe still we can beat.
