$BTW 1 hourly trading volume was about 39.83 million US dollars, 4.4 times the previous average; during the same period, the price rose 0.75%.
Following this data, let's talk about volume expansion.
Any trade has both a buyer and a seller, so increased volume itself does not mean there are more buyers or that funds are flowing in; it simply means trading has become more active.
When volume increases at low levels and the price no longer continues to fall, some people interpret this as a sign that funds are stepping in, but this also needs confirmation from subsequent price action.
Do not change your plan based on a single number, and do not use borrowed money to bet on any particular reading.
