IOST is one of today's top performers. After a long bleed where almost 30% of IOST's value was lost, this token has seen a nice bullish inflow again.
With BTC performing quite well, it's natural that alts are following. The key here is to select the better-than-average performing alts and ride the wave. Be aware that IOST is highly correlated to BTC's performance, so always keep an eye on BTC when trading alts.
Happy trading!
