Imho, a new investor should not buy any domains within at least 6 first months. Educate yourself. Intuition comes after many years, but basic facts are openly available. The last but not the least, determine what inevitable service providers may de-facto rip you off. This applies to some domain auction platforms in particular. And, try to avoid unnecessary related spending. I mean participating in auctions where shill bidding happens or happened before, or where some 2nd highest bidders do possibly (under the table) receive a bounty from the house for being the 2nd - so they would try to bid you up, but without winning themselves...
