Although the whole market is red, I'm very much afraid of holding ETH now. In my opinion, ETH was fluctuated to its ATH when people were more interested investing in ICO. Nowadays ICO is almost dead. That is why it has less demand. I don't think it will get another ATH soon.
What's your thoughts on it? Should I hold now?
No one will give you a definite answer, if you start to panic, the best choice is to sell ETH. I'm guessing the market will come out of red because bitcoin and eth will grow steadily in December.
