With sudden surge in Altcoin price, more and more people are buying altcoins. But, If we look at the price of low priced coins, there has been a huge rise in value of this coins. And if we look at price history of most of the altcoins, we will find a cycle that happens every six moths or a year, wherein the price of Altcoins increases and in a month this gets dumped and gets traded for Bitcoin resulting in massive price increase for Bitcoin.
The last time this kind of surge happened was in May and June, price of most of top 10 coins like XRP, NEM, ETH, etc was around this time. This was followed with dramatic fall in the value and increase in Bitcoins price in August 2017. Since, Bitcoin price keeps on rising, the USD value of all Altcoins also rises but then if we look at satoshi value from now and then it is almost the same.
This may or may not happen this time. But looking at over 800 billion dollar market cap of all cryptocurrencies and BTC dominance of around 33 percent, if and when, the altcoins are dumped for BTC, it will easily double the value in USD from now.
I agree,in my humble opinion we dont need to calculate our gains using USD,instead we need to look in satoshi value.I am just waiting for the BTC dominance to fall below 28 then will start buying more.
