The answer to op, that nobody knows if it will go up or it will fall, because nobody can determine the price of bitcoin even in next 30 minutes you cant predict it accurately, so from observation bitcoin price may go up now and fall in the next hour,
Even in less than an hour after that the price change of Bitcoin traded changes.
Being involved here by itself must be learned and enjoyed by anyone so that the answer to questions like the one asked by op can be obtained by itself.
Easy for those who are willing to learn it and difficult for those who ignore it.
If people want to pay attention to how Bitcoin Price fluctuates, then one of them will know that it happens because it is influenced by supply and demand including sentiment. This is the basis so that a calm attitude when watching the market is formed.
