=====================================
Bitcoin Block Halving prediction
=====================================
bc=884882
gbt=1231006505
bbt=1740246777
This is average time to mine a block
(1740246777-1231006505)/884882
bts=575.4888182957520937796296
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Sun Feb 27 13:18:59 UTC 2028
-------------------------------------
Next palindrome will be 885588
predicted to happen at this time:
Thu Feb 27 10:44:32 UTC 2025
-------------------------------------
Current mining epoch number is 438.
The next fortnight happens in block
885024 and probably around this time:
Sun Feb 23 16:34:56 UTC 2025
