Bitcoin.
Easy to buy, harder to mine.
As a newbie you are, to mine Bitcoin it depends on two things.
1. Your electricity must be very cheap.
2. Your pocket must be heavy.
It costs a lot to mine Bitcoin in 2025 and its only getting started, mining isn't for many people anymore, there are also some things that can happen after you get everything running.
A hardware part can die on you, how long your equipment will last will always remain a misery.
I will choose to buy and hold or else I really want to mine as a hobbist.
