For the newcomers, its definitely a chance to invest in crypto and bitcoin. Although Bitcoin is at 8000$ but all the altcoins are near their all time low. So we can buy bitcoins first and then invest them in altcoins. As soon as bitcoin dominance decreases we will see big movement in altcoin prices.
Why would you buy bitcoin and use it to invest on other crpyto currencies? You can just use that money to buy the altcoins directly. You will just waste your transaction fees on that. Also, if I will be that investor, after I buy btc, I will never use thay nor sell it this time since the possibility of it getting higher is not 0, bitcoin is volatile so it's either pump where I want it or dump where I can invest again my money.
