Low volatility means there's low trading activities going on and this isn't just in the Bitcoin but also in altcoin market because all cryptocurency are getting affected by the bear market and not just the Bitcoin market. Altcoins are losing value more than Bitcoin therefore I don't think people are gaining more trust in altcoins by shifting their investment over there, bitcoin dominance is also increasing as more people are selling their altcoins to buy Bitcoin.
Bitcoin halving is coming so Bitcoin is gaining more popularity than altcoins, after the halving of Bitcoin reward and during the period everyone is assuming that the bull market will start people will start shifting attention to altcoins and that's so they can profit from altcoin.
It’s very strange to hear that now someone is selling their altcoins, what’s the point? If the idea is to sell altcoins and buy bitcoin, then this is also not the best idea now, as for altcoins, then we just need to wait for the altseason, I think that we will still have to wait out the fall and winter, and during this time altcoins may well lose 20 -30% in price. The bear market this year for altcoins is merciless, but perhaps those who are more patient will be able to make a good profit in the bull market.
