No I don't think it has exploded just as yet. When the super-bubble really explodes, only a tiny fraction of altcoins is going to survive. It will be a real bloodshed.
Can we say that the dirt has been cleaned and we can now invest at the right price?
Maybe the dirt has settled for now. I have no idea. Maybe it's safe to invest, maybe it's not. It's anybody's guess. But this is nowhere near the kind of bubble burst I anticipate we are going to witness in the future.
I agree. A real Bubble explosion will come.
We have so many useless altcoins. Many "better and faster" bitcoins also...
I hope we can have more time before that. I expect to see an altcoin pump before.
However, ethereum, as op mentioned, is in a very interesting price now. Its also more probable that it will survive a bubble explosion
