No one is interested in technological superiority any more. All of that extra implementations in shitcoins that are copying bitcoin and adding some cool and completely unnecessary and useless futures like "Untraceable" "More Decentralized" ... bla bla bla... are nothing but a bullshit  (Do you really think that  authorities will not be able to "track" your payment if necessary?) Decentralized ? The same authorities will bring down any server within minutes if necessary. All this is a compete bullshit. Time for speculations is also gone, because cryptocurrencie rates are already controlled by financial institutes that are making hundreds of million dollars trading them. For us (Regular crypto investors) the best choice is to find a good POS coin with reasonable interests and invests in it now.
