Big Bitcoin investors went all-in on purchases last week. They scooped up more than 39 thousand units of the currency — the equivalent of about 3 billion dollars. To top it off, spot index funds (ETFs) also attracted an additional 924 million dollars in new investments.

All this activity provided a strong push to the price: the cryptocurrency took off from the 65 thousand dollar level and surpassed the 81 thousand dollar mark, only to pull back slightly afterward to the 78 thousand dollar range.
