I´m also a believer in the technology, especially of those coins that I have invested in after some hard study.
We will see many coins, like in the past, that will disappear and lose influence. And that's good!
One thing that I don´t agree with you, is your very bearish prediction, I would also like that it developed like you draw it, but I really think it will reach higher values, earlier than you mentioned.
Btw, some of that cards you don´t have are really rare... I don't know why, but also quite famous.
