The volume has increased recently and it matches the level of 2017 dec. This shows that whales are definitely back. Added to that some new investors are also entering the market. We are not much away from the bull market anymore.
Bitcoin is likely to go over $50k this year.
I agree with your opinion that bitcoin will definitely rise again and will be more expensive, attracting large capital investors to invest more money.
Today the price of bitcoin has reached USD 6,510 and my prediction is still up. This increase is a positive sentiment that is a sign of crypto revival. But to reach USD 50000 I think it can't be achieved this year, in my opinion the most is USD 10000.
