Libra has nothing to do with Bitcoin, it is just an idea on paper with a high chance of failing. Yet complete ignorance of the good part of the crypto community regarding Libra perhaps influenced the increased demand at one point, but the price is starting to go up in moment someone (Bakkt) is start to pump money in Bitcoin.
I disagree. When Libra was officially announced, the whole world noticed and it was all over the news and it obviously has a direct relation with BTC. BTC too had a high chance of failing initially, until it took off later on which is why Libra could become a strong contender to BTC in the future.
In a time of stability which we have right now, supply and demand are almost equal - it just shows that cheap coins are not too interesting for most investors.
I agree with you here. Most altcoins are irrelevant now and this can be clearly seen by the high level of dominance by BTC these days(Close to 68%).
