I have btc, ltc, doge, moon, hobonickel, cat, rpc, and earthcoin.

Earthcoin. It's one of the few lately that appears to actually take itself seriously. Or maybe it's just coincidence that most altcoins I read about are jokes to a degree.

I'm not going to waste too much time on Coinye, but I do want to at least mine some. Joke coin coins are fun, as long as the joke is funny. Coinye also seems to have a low barrier to entry for novices, so there's that.

It's so easy for a person to claim they were hacked and didn't make the transaction. I've heard stories of folks even getting phone calls from PayPal asking if they'd like to dispute because it was suspicious. I sold some dogecoin on eBay and I got lucky.

I have heard that if you're going to use PayPal, at least use the send as gift option.
