There is no harm in buying bitcoin at this time, because bitcoin prices are predicted to continue to rise. So do not worry we will experience a loss because the profits will come to us in the future. Stay patient and never panic to sell the bitcoin we have. Buying as much bitcoin as possible with the money we have can make us achieve satisfactory results.
I wouldn't trust the predictions too much. I could remember similar predictions from 2014, which claimed that BTC will rise to $10,000 per coin by 2017. It actually went down by 80%, to $200 per coin in 2016.
