More and more people are interested in what Libra is and how it is different when compared to BTC, but this is indirectly benefiting BTC in a big way leading to the recent rally. This will probably look very small when compared to the upcoming Halving rally in 2020.
Why should bitcoin price rise because of some FB coin, this has nothing to do with each other? You and many others saying that people buying bitcoin because they are interested for Libra, but how familiar I am with FB project, users will be able to buy Libra only with fiat and then transfer it to other person/s or buy / pay some goods or services. Value of Libra should be pegged with $, € or any other fiat currency, so it is something completely different from bitcoin.
Price of bitcoin is going up because period of accumulation is over, and if you look history of bitcoin there are some patterns which are repeated every few years.
