Obviously it's a buying opportunity. Buy some more ETH, next year it will be ETH year.
If you don't have at least 100 ETH you shouldn't even be here. Every crypto investor need to have some ETH.
The way you are expressing it is not right, who told that ETH holder should have 100 ETH, everyone has their own limit and it is not compulsory that everyone should have ETH. I dont belive the ETH developer as he is not a right person to be belived, in his last statement he itself has declared that he is not investing in ETH rather he will convert all coins to fiat currency and invest in real estate or gold. So how do you think that others should invest in ETH. When bitcoin raised even ETH price is also got crashed so it is better to invest in BTC which is much more secure investment.
The way the amount of ETH in circulation increases, very soon all the ETH believers will have 100+. It's really more inflationary than USD.
