I like Litecoin paying the most (superfast and supercheap) but I am not afraid to pay with Bitcoin.
Have you ever tried crypto payment transactions with ETC and ZIL, I saw both crypto nothing in the vote, apart from cheaper fees both crypto are super fast in the payment process.
If you don't believe me, maybe you can try, I guarantee you'll like it, I've done it hundreds of times in payments with ETC and ZIL.
For now I am more comfortable in paying using the two crypto that I mentioned.
altcoins are rarely accepted. i have not seen any merchants going to accept ETC or ZIL. if an altcoin is going to be accepted, it has to be used by the community, dogecoin is being used in casinos that why there are some businesses that use and accept it.
there are more merchants accepting ETH than any altcoins but it's got to be BTC that businesses like the most.
