There was a rapid growth in bitcoin price in last 2-3 months when it was announced Facebook is going to launch its own coin, called libra coin,
Now its already in cold store, due to US and EU agencies interference.
I saw in coin market cap, its only general information about libra coin, but no technical data is available yet.
It is definitely because Libra is still yet to approved thus it is yet launched. Although it has a prior description but still it hasn't yet been used so no data been produced. We cannot further say that it will be going to alive nor dead because Libra is in still on its own progress. So imo if coinmarketcap isn't yet producing its own data then who are we to conclude such analysis, right?
