i have that belief because i see the Ethereum community is very large, and they will be ready to support ETH.
Yes ETH is still struggling when compared to last year but we see it is slowly gearing up. ETH is the king of altcoins it will not lose its reputation as it is. Yes few altcoins are growing now. Most of them have still faith in ethereum and in most of places they have started transactions as well which is a good sign for future. I believe it will bounce back very soon
The entire market is struggling not only ethereum, definitely it is a long term investment where you have good profit. Patience is key for success, have faith in ethereum and hope for the best.
