You might be crying a lot or throwing fists in anger at your computer far more often than with Linux Mint. There's nothing wrong with wanting to try something new but be aware that using a different distro will be a different experience from the one you lived with for long enough, or from MacOS or Windows. Especially one like Alpine Linux which has its fans, currently #29 on the "main" list of Distrowatch but there's not much mention of it in the same sentence as Debian, Fedora and other top distros.
A few users, including me, seem to have trouble getting any attention about Slackware these days. Imagine talking about Alpine Linux? About Void Linux which also has its "cult" and seems to be very well made? The community in favor of Alpine would be as great as that for Linux Mint, but the main difference is it will be much smaller. You will want to be helped as quickly as possible when desperation strikes.
Note that osprey above offered five links. You will have to read and pay attention to instructions much more often than asking others for help with this Alpine Linux. Some people don't like that style, they prefer communication.
(Maybe this is a good idea for a portable phone. On the front page of Distrowatch now, there's news about a new release of Postmarket OS, which is based on Alpine.)
I hope you aren't seriously going to change completely from one Linux OS to another. You could remain using Mint primarily, and have Alpine or other distro as "fun project". Then you could just stop using it and forget about it when you get tired of it and/or if something else catches your interest.
