Bitcoin and crypto currencies are Volatile thats why things like this happens,but if you look for a long perspective then you will find whats the benefits of this.
Maybe this is not for those who wanted to invest and make a living here since this is not design for short term profiteering but still there are many advantage that we have to agree.
Just like what everybody says here (those who have been here and profiting for long time) that Invest what you can afford to lose and you must be willing to wait even if this may take long time to increase.
