=====================================
Bitcoin Block Halving prediction
=====================================
bc=896005
gbt=1231006505
bbt=1746822887
This is average time to mine a block
(1746822887-1231006505)/896005
bts=575.6840713120224641352848
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Feb 29 22:15:55 UTC 2028
-------------------------------------
Next palindrome will be 896698
predicted to happen at this time:
Wed May 14 11:23:56 UTC 2025
-------------------------------------
Current mining epoch number is 444.
The next fortnight happens in block
897120 and probably around this time:
Sat May 17 06:52:54 UTC 2025
