I'd recommend litecoins. Litecoins definitely one of the safer options when it comes to cryptocurrencies. While I don't quite remember the specifics, I was told that the technology based on them is solid. Much more than a lot of other cryptocurrencies. When I first dealt with litecoin projects (I worked on litecoinlocal's logo and website design) they were about 4.00 usd a coin. They've gone up since then, and I don't think they're going to be going down by much. That's my 2 cents. Great post!
