I think this speculation is the most accurate. We have seen ethereum going down to $130 not so long ago, so I guess it may drop to $100. Litecoin is unbelievably stanbe lately, dropped only to $20 once, so I guess it is not likely to go lower than $25. As for bitcoin, it grew som incredibly fast that I wouldn't be very surprised for it to get back to $900, for even it reaching $1k in January was unbelievable. Its contemporary price is too good to be true.
