this is keystand points from both psychological and value people definitely feel uneasy with segwitx2
maybe for the uninformed it is!
but in reality the "wall" is nothing compared to the total trading volume of each day on each exchanges. it is actually laughable when you think about it.
also it is all the misinformation about SegWit, SegWit2x, UASF,... that is making people doubt stuff. but facts are SegWit currently has a total support of over 90% and with nodes on the ready for months if the miners lock_in SegWit then it will be simply activated on that date! and the support is already high!
maybe people are more interested in "ifs" rather than "facts"
