I agree on taking timely profits and thanks for that wise remainder, BUT , Well until it crosses at least 60% of other assets market caps and have some comparable data to traditional markets i would not call ti a bubble. Here a good comparison.

bitcoin is smaller then silver :-), and altcoin is smaller then bitcoin ...

And now money from Stocks and Traditional markets has only "Started" to come to altcoins....

So if anything, and even if this is a bubble, it is the tiniest bubble of everything in the world, and will probably have to go 1000 times before bursting. I mean not guessing anything, plain facts...

as govt's ;legalize , proper market money starts to flow...
