=====================================
Bitcoin Block Halving prediction
=====================================
bc=949770
gbt=1231006505
bbt=1779001687
This is average time to mine a block
(1779001687-1231006505)/949770
bts=576.9761152951606229291060
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 15:06:43 UTC 2028
-------------------------------------
Next palindrome will be 949949
predicted to happen at this time:
Mon May 18 11:49:25 UTC 2026
-------------------------------------
Current mining epoch number is 471.
The next fortnight happens in block
951552 and probably around this time:
Fri May 29 04:44:18 UTC 2026
