Newbie here asking for an advice

Greetings,

I am new to this Forum and generally to the Crypto Mining world. I plan on building a mining rig with 6 RX 5700 XT 8 GB GPUs in July 2021. So I wanted to ask you guys whether it is worth it? I am currently leasing my hash power of my gaming PC for NiceHash but I don’t know whether it will be available long term. The electricity in my country is about $0.074 kW so it will not be a problem.

Thank you for your answers in advance
