What is currently the best crypto currency to mine

Hey guys. I’m thinking about starting to mine crypto but I’m unsure of which currency I should go for. Also I’m not too sure whether to build a GPU rig or to get a ASIC miner.

Any help would be much appreciated

Spend some time on Youtube. Theres a ton of info

Okay thank you. Do you perhaps know any specific videos on this topic as I have been searching for quite a long time and havent found the answer. I believe its die to the fact of my inexperience
