I think Byteball is mostly undervalued because of it's confusing name and the Gbyte coin value instead of Mbyte coin value.
I personally think it sounds better to own 1000 Mbyte coins instead of 1 Gbyte. would you rather own 1000 MIOTA or 1 GIOTA. Same thing but what sounds better?
I believe if IOTA delivers it will be huge and I am holding quite a bit of IOTA long term. But I also realize IOTA's focus is machine to machine transactions not human to human interaction. This is where Byteball comes in.
I always remember hearing about Byteball but never felt the need to learn much about it until I started doing research on DAG. I always thought Byteball was complicated to say and sounded a bit juvinial so it must not be a serious coin. Boy was I wrong. After using and testing the Byteball wallet over the last week I decided to make Byteball one of my long term coin investments and make it a good share of my coin portfolio.
I am lucky I discovered Byteball before it takes off. I can thank the Byteball name and Gbyte coin value for that ;-).
