It's good to buy ethereum right now because it has dropped considerably from now on I think many traders are buying and holding on bitcoin and ethereum.
I agree with that opinion, it is good to buy now simply because the price of ethereum are down and it is your opportunity to buy a lot of it. Furthermore, I think its up to you if you want to hold your ethereum or not but I suggest its better to hold now rather than to sell it now because if you sell it now your income will totally low.
