question About NNNNNN

[Hitbones]

are NNNNNN worth it to reg ?

i see lot of recent sales in namebio

for example this one

what is good with these numbers ?
is because there is two 5s ?

i understand if there is 3 same numbers or 4 same numbers ..etc

im surprised

can anyone tell me what makes it valuable ?

Because this domain end with 365. This deal is not bad, can flip and sell between 900-1.2k.
