=====================================
Bitcoin Block Halving prediction
=====================================
bc=896003
gbt=1231006505
bbt=1746821448
This is average time to mine a block
(1746821448-1231006505)/896003
bts=575.6837502957576082249632
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Feb 29 22:10:18 UTC 2028
-------------------------------------
Next palindrome will be 896698
predicted to happen at this time:
Wed May 14 11:19:08 UTC 2025
-------------------------------------
Current mining epoch number is 444.
The next fortnight happens in block
897120 and probably around this time:
Sat May 17 06:48:06 UTC 2025
