As per a recent comment this thread is meant to voice contrarian opinions, that is anything this community tends not to agree with. Thus I ask you to post your contrarian views and upvote anything you do not agree with based on personal beliefs. Spam and trolling still needs to be downvoted.
Bitcoin and a few different altcoins can all coexist in the future and each have significant value, each fulfilling different functions based on their technical details.
That doesn't seem especially contrarian to me, given the base premise that cryptocurrency has legs in the first place. At the very least, it seems obvious that easy-to-trace and difficult-to-trace transaction systems have different and complementary niches.
