Absolute maximum of "coins" in a bitcoin fork's chain ?

[Lolcust]

Hello, I have a simple and maybe stupid question:
Were it not for subsidy getting halved, how many coins would a chain be able to contain (the blockchain in total, not individual transaction) before problems would start ?

In general there's no limit, number of coins is just a number and you only indeed an appropriate data type. With an implementation similar to Bitcoin, where units are stored in 64-bit integers and a coin is 100M units, you can have up to 184B coins.

I think this question belongs in the technical support section.
