There is no where Bitcoin market value will return to the level at which most of the altcoins are presently because Bitcoin has come a long way that its value cannot in any way return to any near altcoins value, not even ethereum nor Bitcoin Cash or which ever one you can think about in all the alternative coins. And Bitcoin is going to help the financial system in the world in one way or the other.
I know a lot of people are very enthusiastic and hoping that things would change quickly and you start seeing the bulls in actions, but if things were that easy, every market will just be busy switching trends anyhow immediately. This is not a pump and dump market and all these things take time for a very strong market.
I would not be expecting something serious this year at all, and even if we are to get to the previous ATH, we may need to wait a while to achieve that, hopefully by December. But when looking at the positive aspects, halving may trigger another explode of markets. Even it is far away from now, we cannot ignore what it could do with price levels of bitcoins potentially.
