Any altcoins with high growth potencial under $10
Individual coin price doesn't have any bearing on anything. You need to look at marketcap.
For example:
A) $1 coin with a supply of 1 billion coins... it takes $1 billion to double the coin price;
B) $1000 coin with a supply of 1000 coins... it takes $1 million to double the coin price.
So an injection of $1 billion into both markets would mean the $1000 coin is a hugely better investment.
But as coin price is the topic, I'll second AdEx, Status and Ark, and add Aragon and BitBay. And also XRP
Really though there are plenty under $10 individual coin price that are worth a look.
