People who are refusing to deal with altcoins, specially when Bitcoin is in trouble are dumb IMO. There are so many of them if you catch 10% of pumps you'll be good as much as Bitcoin is failing.
And why couldn't altcoins fall just as hard or harder than bitcoin (just like silver tends to fall faster than gold on the way down)? Just because they might not have done that so far, doesn't mean they won't in the future.
You seem to be assuming that altcoins will take up a larger market share for sure.
I am not sure what you mean. Are you saying you are just buying to sell to a greater fool?
