Many altcoins holders now are really frustrated and i really feel there loss, but i think bitcoin will continue to be stronger and many altcoins will crashed, that's why many investor are choosing to put there money on bitcoin over altcoins now.
I still don't understand why people invested so much on the alts. In the world of crypto-currency, there is no room for 100,000 different coins. At the most, 100 or 200 may survive for the long term. The problem when we have so many different altcoins is that even if a project is good, it gets drowned out among thousands of other crap projects. And what surprises me the most is the resilience from the investors, who continue to pour down their hard earned money in to these shitcoins again and again, despite incurring crippling losses everytime they do so.
In the end, people would always ignore the copycats unless the latter could prove that they are substantially better than the original product. In case of altcoins, this hasn't happened. They are not superior to the original product (Bitcoin) and most of them were created just to fatten the pockets of the promoters.
