I think BTC will go a lot bigger than 20k but time is a big factor now. The media wont talk as much about BTC until it starts growing again but it cant grow without media coverage. Mass adoption will bring new investors in, this will alert the media and if crypto finds a place in our everyday lives you can expect BTC to go a lot over $20k. I personally believe that it can hit close to a million per coin but only if cryptocurrencies as a whole become adopted worldwide. If they fail at mass adoption we could see BTC going back to hundreds of dollars or even less...
