Price predictions are very hard to make because of unexpected circumstances in the global market. I think there can only be a general idea about the price, if some events take place and influence the price.In general I would say, if you are a supporter of cryptocurrency and specific altcoins you believe in the main idea and therefore you invest or hodl crypto.
So I believe that the global market will adopt more to cryptocurrency, but giving a price range for coins seems for me almost impossible.
