Bitcoin Block Halving prediction
=====================================
bc=880286
gbt=1231006505
bbt=1737510112
This is average time to mine a block
(1737510112-1231006505)/880286
bts=575.3846268319309497925108
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sat Feb 26 06:55:38 UTC 2028
-------------------------------------
Next palindrome will be 881188
predicted to happen at this time:
Tue Jan 28 01:51:48 UTC 2025
-------------------------------------
Current mining epoch number is 436.
The next fortnight happens in block
880992 and probably around this time:
Sun Jan 26 18:32:13 UTC 2025
