It could be either. In the end, it all comes down to supply and demand as per usual. And if you're going to the "manipulation" route, it could also go either way. Remember, the "whales" can manipulate the prices(to a certain extent) both in an upward trend or in a downward trend.
And again, all that matters is that there will be increased market liquidity.
