=====================================
Bitcoin Block Halving prediction
=====================================
bc=880649
gbt=1231006505
bbt=1737733411
This is average time to mine a block
(1737733411-1231006505)/880649
bts=575.4010174303071594844716
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sat Feb 26 11:42:28 UTC 2028
-------------------------------------
Next palindrome will be 881188
predicted to happen at this time:
Tue Jan 28 05:52:32 UTC 2025
-------------------------------------
Current mining epoch number is 436.
The next fortnight happens in block
880992 and probably around this time:
Sun Jan 26 22:32:53 UTC 2025
