We can maybe expect to hit the previous high around $1.84 but I don't think this month or next month if it can break the past ATH, which is around $3, maybe this coming altcoin season next year we hope to see some good news about XRP might around June or July is the time that I know for altcoin season.
$20 is a big ask this bull run but not impossible - it would give XRP a market cap of $1.15 trillion which is a lot yes but XRP has the potential to hit that with how big its going to be across the world.
For me though my target is $10 next year, that is definitely possible.
