Actually mathematically BTC will reach Infinity someday.

That is because there is a fixed amount of BTC and the amount is dropping (by wallet loosage for example) and the amount of humans is rising.

Therefore it is mathematically proofed, that BTC - when used as currency - has to reach infinity value if the timespan is long enough. That sad, the timespan of BTC is not infinite and it will get replaced when it is not longer suitable.

10k is therefore a valid amount for 1 BTC - IF btc is used as a regular currency, which we will see.
