Interesting choice of topic @spiritualmax

The most important reason of all is lack of trust. The thing about trust is that it takes many years (probably one generation of investors in our case) to get it back.

With bitcoin things are easier, simply because so much depends on mass media. So if mass media narrative will be to promote crypto, then they will talk mostly about bitcoin.

Altcoins have been bleeding out for very long and most of them do not have resources to work on their brand. To change their image.

ps.
10th reason indeed shocked me :P :)
