=====================================
Bitcoin Block Halving prediction
=====================================
bc=946446
gbt=1231006505
bbt=1777034373
This is average time to mine a block
(1777034373-1231006505)/946446
bts=576.9238721238484563847737
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 15 23:52:27 UTC 2028
-------------------------------------
Next palindrome will be 946649
predicted to happen at this time:
Sat Apr 25 21:11:28 UTC 2026
-------------------------------------
Current mining epoch number is 469.
The next fortnight happens in block
947520 and probably around this time:
Fri May 1 16:46:29 UTC 2026
