=====================================
Bitcoin Block Halving prediction
=====================================
bc=896987
gbt=1231006505
bbt=1747412420
This is average time to mine a block
(1747412420-1231006505)/896987
bts=575.7110630242545050769909
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 1 06:08:16 UTC 2028
-------------------------------------
Next palindrome will be 897798
predicted to happen at this time:
Thu May 22 02:02:01 UTC 2025
-------------------------------------
Current mining epoch number is 444.
The next fortnight happens in block
897120 and probably around this time:
Sat May 17 13:36:29 UTC 2025
