=====================================
Bitcoin Block Halving prediction
=====================================
bc=924173
gbt=1231006505
bbt=1763482212
This is average time to mine a block
(1763482212-1231006505)/924173
bts=576.1639117741897088643480
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Mon Mar 6 18:13:08 UTC 2028
-------------------------------------
Next palindrome will be 924429
predicted to happen at this time:
Thu Nov 20 09:08:29 UTC 2025
-------------------------------------
Current mining epoch number is 458.
The next fortnight happens in block
925344 and probably around this time:
Wed Nov 26 11:34:59 UTC 2025
