Cashed out my bitcoins a few years ago (a little too early, oh well) and I'm looking at getting back into it. I'm more interested in Alt-coins etc, since there seems to be a few problems with BTC imo.

I was just looking for a little advice on good coins to be watching. I'm looking for stuff with real innovation and not just one of the 100s of identical coins I've seen.

After a fair bit of reading, I still haven't found anything I feel I can fully go behind. I'm not massively interested in spreading my bets and using exchanges to profit, I'd just like a coin that, after a little research, I feel that I could invest in. I'm happy to research, so if anyone has any links to any information, I'm happy to have a read. If you just want to recommend your coin, tell me why it's good and different please.

I'm not looking for a cheat sheet, just a bit of friendly advice.

Cheers
