For example, for every $1 that LTC goes up, is 1% of LTC's total value, at the time of typing.
BTC has to go up almost $115 dollars to go up by 1%, at the time of typing. This is mitigated by the sheer volitility of BTC , but the line of thinking is still valid. In turbulent markets, look to stable currencies like USD/USDT for your growth charts, not BTC comparisons, unless you're a diehard BTC trader or HODLer.
But if you're just long-hodling BTC , odds are you aren't trading against USDT, and either way you'll be fine. I personally think being patient and long-terming BTC with small hedges in LTC and ETH are the best idea, but for the swing traders, shows a lot of promise.
