I think bitcoin and many top coins had a nice bull run for the first half of 2019 and have been correcting that bull run since then. This correction should likely end this month similar to 2018 and then next bull run should start.
Everyone is very positive about the current situation, but we don't know whether we might see a bull run or not. Most of the potential altcoins, decreased a lot in the market, which we might see an improvement when the price of Bitcoin crosses again 10000$. Let's see what happens in the coming year we have to wait and see.
