yes, i did worried a little at first cos usually when too many ppl join in it's usually a sign market is peaking out and may crashes soon but that is under conventional investment scenario but u need to understand bitcoin is unconventional investment so i would assume it may not behave the same. 

yes, i'm taking chances but these ICO's are soooooooo tempting with 1000's of % gain something unheard of & may never see in my lifetime ever again. Not everyone may agree with me but i think risking small money for big money is worth a risk taking. i hear many said btc is here to stay and i totally agree with that unless all ICO gone with the blink of an eye. just my opinion
