Monero should be the number one, sadly no one is using it, absolutely anonymous and cannot be traced like most other popular cryptos
.
I end up using ETH since it’s pretty fast and has low fee’s. I don’t hold any coins though, only buy them before I order something, so fluctuations usually don’t affect me at all. I just have some money on my kraken account that can be traded into any crypto I want (usually in 1-5 mins), than off to my wallet, and off to the vendor.
Just glad I never have to fuck with MG or WU ever again.
