Is it worth building mining rigs 2026?

it depends...

I wouldn't recommend building am5 rigs but am4 is salvagable

@RyzenTheThreadripper If you have a decent amount of capital and you want to start a side business, expect it to take a few years before you see an noticeable profit. The easier way is to buy a new computer and then "pay off" your intial payment by mining XMR.
That said though, if you think the price of XMR will rise long term, then yeah building a mining rig is a possibility. Though in this situation I'd say it is way more cost effective to just buy XMR.

@xenu I'm not interested in buying monero i'm more interested in mining monero for the fun

@RyzenTheThreadripper Based. Yeah it is pretty fun. You may be interested in solo mining then because, while it is a lottery ticket, you can potentially get an entire block all to yourself. I solo mine and I've never won. It ain't much but it's honest work.

@RyzenTheThreadripper No I think its more worth to just invest into monero but im not certain

@RyzenTheThreadripper just buy used pcs from ebay or smth look for ryzen 9

@RyzenTheThreadripper just buy monero

i have built mining rig with 5950x, ddr4 prices are okayish
