I believe that the time will come, slowly the altcoin starts to crawl up now and my hope is that by the end of the year it will be like this last year. The number of short positions fell to a historic low.This suggests that the bears have exhausted their strength, and perhaps soon we will see the growth! I hope so.
Everyone is believe that time will come that all altcoins will rise. Many are expecting that this year is year of altcoins dont stop believing I know that last year all altcoins become in red now I know altcoins will continue rise and their will be in color green. Expect and believe still be positive.
It is a tough call for all alts to rise though. But there are few who are making their way up on the stage, so I don't think we should have to recognize each of them as somewhat some of it are having their golden time pumping. Besides, you won't be investing all of 'em, and I bet you'll just pick among on the top list.
I think that only few of the altcoin can make it and follow up once the value of BTC soar high within the value of $20,000 - $30,000 because obviously top ranked altcoins has a large marketcap and the volume is high which is the reason it could rise their value.
And holding them for a long term is also good but it will depend if the developer will not left the project or sell their supply which happen before in some altcoins.
