I think the value of chips will slowly continue to go down but then stabilize and begin to rise if it drops to $500 or $600.
I think random chips with bad western letters will slowly drop as there are 456,976 four letter domains out there. Certainly no shortage.
I believe 4 letter domains with strong western letters will at least meet the value of chips if not surpass them at some point.
4 letter pronounceable domains will continue to rise well above chips, if they are really pronounceable, thus brandable.
4 character domains are rarer than 4 letter domains for the simple fact there are less digits than letters. Therefore I believe LNNN.com/NNNL.com (Only 10,240 of each without 4s, 0s, vowels or vs) and to a lesser extent LLNN and NNLL domains will rise in value, especially those with doubles or 8s. They are not as rare as the LNNN/NNNL but much rarer than 4 letter domains. I have seen some movement with these, but they are still undervalued in my opinion, based on how pricey LNN/NNL/LLN/NLL .com domains have gotten.
