Can we have something more specific and new about why need to hold the coins other than we need to hoping that something will happen at end.

Then why are you here in the forum? I think that people here in the forum is very interested in cryptocurrency and the ones that are making FUD and saying something against cryptocurrency is just making some issues with it and not actually interested with it, As you can see if you would look at the past movement of price of bitcoin you will know that this type of thing happen back then, And it actually recovers back up again and making a bull run on its recovery, I say you just need to look at bitcoin's price and movement for you to understand that this is not the end.
I've come to realise that most persons are only concerned about the profit they make out of the market. When the profits are not forthcoming, they tag the industry 'dead' or 'scam'. They forget to check the history to acquit themselves with the movements and how despite the terrible situation, the market bounced back and met a greater ath. Am not negating the importance of taking profits and getting the best out of opportunities, but we need to study the trend of the industry and not settle like mere spectators.
