This is really interesting! Actually, apart from BTC, I have been looking into altcoins like ETH and LTC right now. Ether was highly recommended in one of the threads I stumbled upon, saying that it's the "must- have" for 2018.
Are there any other altcoins that you would recommend? Huhu. Of course I want to invest my money on something that would be more stable and consistent. And to me, since you were talking about altcoins that are being developed to become actual currencies, could be a great opportunity!
