I have sold all my coins that I had on my balance to buy ETC to participate in recent Calypso's fork. Current price is 1,6$, what do you think - is it worth to hold it or better to exchange on some oldy like WAVES or any other like that?
You got it all wrong mate. The fork was Callisto (CLO) not Calypso's fork and the snap ought to happen yesterday but I don't know if the fork have replay protection. However, the coin holder are said to earn interest for holding the coin for long enough(at least a month or 2). But don't be blind by this to the extent of investment too much.
Is that means if there are two forks were happening in this month in ethereum classic? It looks like a horrible thing. ETC was definitely doesn't know about these hardforks. The team has announced that in a single tweet on the official twitter, because if you are willing to buy etc due to the fork coin and then it will become useless if you are holding it.
