=====================================
Bitcoin Block Halving prediction
=====================================
bc=877159
gbt=1231006505
bbt=1735619468
This is average time to mine a block
(1735619468-1231006505)/877159
bts=575.2804083633544621277760
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Fri Feb 25 00:31:49 UTC 2028
-------------------------------------
Next palindrome will be 877778
predicted to happen at this time:
Sat Jan 4 07:26:06 UTC 2025
-------------------------------------
Current mining epoch number is 435.
The next fortnight happens in block
878976 and probably around this time:
Sun Jan 12 06:52:32 UTC 2025
