Zcash breaks the records it cost was around 7btc, i don't invest in it but it was only cryptocurrency besides bitcoin that got my attention.
Also analysing the Bitcoin, Monero and Zcash transactions i would say Zcash is most private, secure.
So, Your words were misleading for me. If you try to compare with the others and this are so far from the purpose of the compares thread.
XMR still hold the secure privacy. And bitcoin still being the king of crypto.
