Its the concept of high betas and low betas. When BTC is declining/crashing, rescue your BTC or any other high beta (strong BTC correlation like for e.g. LTC) in a low beta (or fiat money)… But exchanges like binance, low betas are the best to save your funds.
there are coins with strong (high betas) a poor (low betas) correlation to BTC chart(s). LTC, for example, behaves somehow like using BTC as a “template”
so if you’re invested in LTC and BTC crashes/declines, you should go into a low beta to don’t lose as much money as you would while staying in LTC…
low betas to protect your savings/funds from bigger losses, instead of fiat money like USD respectively
you can translate low betas to “stablecoins” somehow
during last 90 days, XRP was low beta
