You're excited about Bitcoin and its dynamics!

Just to clarify, a block on the Bitcoin blockchain is mined approximately every 10 minutes. The number of blocks left until the next halving event (which occurs when the total number of "blocks" - or rather, units of time - since the Genesis Block reaches 2,100,000) would be around 210,000 / 10 = 21,000 blocks.

As for the timeframe, a block is mined approximately every 10 minutes. So, dividing the remaining blocks by this rate gives us an estimate of:

172281 / (1 block / 10 minutes) ≈ 5.7 days, not years!

The actual Bitcoin halving event occurs roughly every 210,000 blocks, which works out to about 4-5 years on average, depending on the hash rate and network conditions.

Keep in mind that this is a simplified explanation of the complex mechanics behind the Bitcoin blockchain!
