I would like to have some experts response on the topic...
There is no such thing as, "experts" when it comes to a speculative industry such as cryptocurrency. All you have people give out are based on either TA (technical analysis) or FA (fundamental analysis).
I think that this year the altcoins will show stronger growth than Bitcoin.
You must be kidding, right? Don't you know that altcoins move when Bitcoin moves. They dip whenever Bitcoin takes a plunge. Just know it now that Bitcoin is the Dictator-In-Chief in this crypto industry.
