=====================================
Bitcoin Block Halving prediction
=====================================
bc=949681
gbt=1231006505
bbt=1778951801
This is average time to mine a block
(1778951801-1231006505)/949681
bts=576.9776577843951975503379
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 15:33:42 UTC 2028
-------------------------------------
Next palindrome will be 949949
predicted to happen at this time:
Mon May 18 12:13:51 UTC 2026
-------------------------------------
Current mining epoch number is 471.
The next fortnight happens in block
951552 and probably around this time:
Fri May 29 05:08:46 UTC 2026
