There is nothing wrong about the decision if indeed he is sure and confident for a long time. Indeed, it would be better to focus more on bitcoin for now but when they believe there is another potential in other crypto such as Litecoin, because when a more positive season has come it is very possible that large or popular crypto will get a positive impact as well with an increase which is very significant.
Yeah right. If being sure and confident for a long time is enough, I would be a millionaire right now. Grow up, dude.
